Description:Field of the Invention


The present disclosure relates to vibration isolation systems. Particularly, the present disclosure relates to numerical control devices designed for counting and controlling vibrations in mechanical systems using harmonic filters and active dampers.
Background
The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
Vibration isolation systems have been employed in various industries to reduce the transmission of vibrations from mechanical assemblies. Such systems are critical in environments where high-precision machinery is employed. Generally, conventional vibration isolation systems rely on passive elements such as springs, dampers, or rubber mounts to absorb and dissipate vibrational energy. These systems reduce the transmission of vibrations to connected machinery or equipment. However, passive systems are limited by their inability to adapt to dynamic changes in vibration frequencies, leading to inefficiencies when dealing with a broad spectrum of vibration frequencies or rapidly changing conditions.
In many cases, state-of-the-art vibration isolation systems rely on passive methods that are tuned to a specific frequency range. These systems may be effective in certain conditions but are often unable to handle higher harmonic vibrations or vibrations that arise from changes in operational conditions. For instance, passive isolators frequently exhibit limited performance when attempting to isolate low-frequency vibrations or vibrations resulting from machine resonance. Furthermore, conventional systems may not effectively address harmonic vibrations that can propagate through machine frames, affecting both operational performance and longevity of the equipment.
Active vibration isolation techniques have been introduced to overcome the limitations associated with passive systems. These techniques employ actuators or other components to actively counteract vibrations. Active systems can respond dynamically to changes in the vibration profile and offer superior isolation capabilities compared to passive systems. However, such active systems can introduce additional complexity due to the need for sensors and control mechanisms. Moreover, active systems often depend on accurate vibration detection and control algorithms to mitigate the effects of harmonic vibrations, and any failure in detection can result in inadequate vibration isolation. Additionally, the integration of active components into mechanical systems may introduce further challenges related to system stability and noise generation, limiting the overall effectiveness of such systems.
Moreover, some existing vibration isolation systems incorporate filters that are used to block or mitigate specific harmonic frequencies. Such filters are generally placed within the system to prevent the transmission of certain vibration frequencies through mechanical assemblies. While such harmonic filters provide an enhanced degree of control over the types of vibrations that are isolated, they may also experience inefficiencies when operating under dynamic loads or during rapid changes in vibration patterns. Filters are typically designed to isolate specific frequencies, which can result in performance degradation when handling vibrations that occur outside the targeted frequency range.
Additionally, certain known systems utilise machine frames designed with inherent damping properties, aiming to reduce the propagation of vibrations. Such machine frames often incorporate additional materials or structural elements intended to absorb vibrational energy. However, the effectiveness of machine frame-based vibration isolation is often limited, particularly when dealing with high-frequency harmonic vibrations, as these vibrations can still transmit through the frame and affect other connected components. Furthermore, the integration of vibration isolating structures into the machine frame adds complexity to the overall system design, which can lead to cost increases and mechanical failures.
In light of the above discussion, there exists an urgent need for solutions that overcome the problems associated with conventional systems and/or techniques for isolating vibrations, particularly harmonic vibrations, from mechanical assemblies.

FIG. 1 illustrates a vibration isolation system (100) , in accordance with the embodiments of the pressent disclosure. In an embodiment, a vibration isolation system 100 comprises a harmonic filter 102 positioned within a drive assembly 104. Said harmonic filter 102 isolates predetermined vibration frequencies from the drive assembly 104. The harmonic filter 102 may be mounted directly within the housing of the drive assembly 104, such that it effectively interacts with various drive components, including but not limited to gears, spindles, and shafts, which generate or transmit vibrational forces during operation. Said harmonic filter 102 may include mechanical elements such as mass dampers, tuned absorbers, or other vibration isolation structures that selectively target specific frequency ranges. In some variations, the harmonic filter 102 may include adjustable components or tunable parameters that modify the filtering capacity depending on the operating conditions of the drive assembly 104. The positioning of the harmonic filter 102 within the drive assembly 104 enables close proximity to the source of vibrations, allowing the isolation of vibrational energy before it propagates to other parts of the machine.

Such adjustments may be manual or automated, allowing for the harmonic filter 102 to dynamically adapt to changing vibrational patterns, enhancing the system's ability to isolate unwanted harmonic frequencies.
In an embodiment, the drive assembly 104 of the vibration isolation system 100 further includes a spindle that is rotationally mounted and interacts with the harmonic filter 102 to mitigate vibrations arising from rotational motion. The spindle serves as a critical mechanical component within the drive assembly 104, and its rotation often generates vibrational frequencies due to imbalances, friction, or torque variations. Said spindle is aligned in such a manner that its movements are influenced by the harmonic filter 102. This arrangement allows the harmonic filter 102 to target and isolate vibrations directly associated with the spindle's rotation, reducing the transmission of such frequencies to the rest of the machine. The spindle may be mounted on bearings or other rotational supports within the drive assembly 104, providing a stable rotational axis. The material composition and structural design of the spindle are optimized to facilitate the harmonic filter 102 in effectively interacting with the spindle's movement. The placement and configuration of the spindle within the drive assembly 104 enable the reduction of vibrational disturbances, particularly those resulting from rotational dynamics.
In an embodiment, the active dampers 106 of the vibration isolation system 100 comprise piezoelectric elements that adjust damping force dynamically based on the amplitude of detected harmonic vibrations. Such piezoelectric elements generate an electric charge in response to mechanical stress, enabling active dampers 106 to alter their damping properties in real time. When vibrations are detected in the machine frame 108, the piezoelectric elements produce a corresponding electrical signal, prompting the active dampers 106 to respond with an appropriate damping force. This dynamic adjustment provides a tailored response to the vibrational intensity and frequency, allowing for rapid adaptation to changes in vibrational conditions. The piezoelectric elements are embedded within the structure of the active dampers 106 and are connected to the control unit 110, which analyzes vibration data and directs the response of the dampers accordingly. The piezoelectric elements may be composed of ceramic, polymer, or composite materials that exhibit piezoelectric properties, and their arrangement within the active dampers 106 is designed to maximize the efficiency of vibration absorption.
In an embodiment, the machine frame 108 of the vibration isolation system 100 includes a sensor array positioned along the structural members of the frame 108. The sensor array detects vibration intensity and provides feedback to the control unit 110 for analysis and control purposes. The sensors in the array may include accelerometers, strain gauges, or other vibration-sensitive devices that are capable of detecting variations in amplitude, frequency, and directional movement of vibrations within the machine frame 108. The positioning of the sensor array is carefully considered to ensure comprehensive monitoring of vibrational activity, with sensors placed at locations that are most susceptible to vibrational transmission. The collected data is relayed to the control unit 110, enabling real-time analysis and subsequent adjustments to the active dampers 106 and harmonic filter 102. The sensor array operates continuously or at predetermined intervals, ensuring accurate and timely detection of vibration patterns across the machine frame 108, thereby enhancing the system's vibration isolation capability.
In an embodiment, the control unit 110 of the vibration isolation system 100 includes a processor and a memory, where the processor is programmed to calculate real-time vibration frequency data and control the active dampers 106. The processor analyzes the data received from the sensor array on the machine frame 108 to identify vibrational patterns, including amplitude, frequency, and duration. Based on this analysis, the processor determines the optimal response for the active dampers 106 to isolate and absorb the detected vibrations. The memory stores operational parameters, predefined vibration thresholds, and historical data that the processor may use for reference when calculating the appropriate control actions. The control unit 110 communicates with the active dampers 106, sending signals that adjust their damping forces to match the detected vibrational characteristics, thereby mitigating the impact of harmonic vibrations on the machine's structure.
In an embodiment, the active dampers 106 of the vibration isolation system 100 are strategically arranged at nodal points of the machine frame 108. Nodal points are locations on the frame where vibrational movement is minimized, and the positioning of the active dampers 106 at these points enables maximized vibration absorption efficiency. The arrangement at nodal points reduces the transfer of vibrational energy across the frame 108, ensuring that the active dampers 106 counteract the most significant vibrational disturbances. The determination of nodal points is based on the vibrational mode shapes of the machine frame 108, which are analyzed to identify areas of minimal movement. The placement of the active dampers 106 at these nodal points allows for more effective isolation of harmonic vibrations.
In an embodiment, the harmonic filter 102 is further adapted to adjust its frequency filtering parameters based on input received from the sensor array positioned on the machine frame 108. Such an arrangement allows the harmonic filter 102 to continuously optimize its vibration isolation performance. When the sensor array detects changes in vibrational frequency or amplitude, the control unit 110 processes this data and sends signals to the harmonic filter 102, enabling adjustments to the filtering range or damping characteristics. Such a dynamic adjustment capability allows the harmonic filter 102 to respond in real time to varying operational conditions, maintaining optimal isolation of vibrations within the machine.
In an embodiment, the control unit 110 of the vibration isolation system 100 comprises a user interface that permits manual adjustments to the harmonic filter 102 and the active dampers 106. The user interface may include input devices such as touchscreens, keypads, or dials, which allow an operator to modify operational parameters, such as the frequency range of the harmonic filter 102 or the damping response of the active dampers 106. This manual adjustment capability provides flexibility in setting vibration isolation preferences based on specific requirements or conditions. The user interface may display real-time data on vibrational activity and system performance, offering insights into the effectiveness of the isolation system.
In an embodiment, the machine frame 108 of the vibration isolation system 100 further includes a vibration suppression layer integrated within its structural members. Such a vibration suppression layer is designed to minimize the transmission of vibrations across the frame 108 by providing additional damping to the structural members. The vibration suppression layer may comprise materials such as rubber, foam, or composite structures that exhibit high damping properties, effectively absorbing vibrational energy. The integration of the vibration suppression layer into the frame's design enhances the overall stability of the machine and reduces the propagation of unwanted vibrations throughout its structure. The vibration suppression layer is distributed throughout key structural members of the machine frame 108 to maximize its impact on vibration isolation.
The disclosed numerical control device for counting vibrations is an advanced vibration isolation system (100) that enhances the operational stability of mechanical systems by isolating and managing unwanted vibrations. Central to the system is the harmonic filter (102), positioned within a drive assembly (104). The harmonic filter is specifically designed to target and isolate predetermined frequencies of vibration that can disrupt the operation of the machinery. By filtering out these frequencies, the system ensures smoother mechanical performance, minimizing the risk of resonance or mechanical fatigue caused by persistent vibrations.
The system also incorporates a series of active dampers (106) mounted to a machine frame (108), which absorb harmonic vibrations that escape the harmonic filter and are transmitted through the machine frame. These active dampers are dynamically controlled to respond to changing vibration conditions, actively adjusting their damping force based on the detected intensity and frequency of the vibrations. The control unit (110) plays a critical role in coordinating the harmonic filter and active dampers. It monitors vibration data in real time, analyzing harmonic interference and issuing precise adjustments to the active dampers for optimal vibration absorption.
This system is particularly valuable in environments where machinery is subjected to continuous vibrations, such as manufacturing plants or heavy industrial applications. The ability of the control unit to count and monitor vibrations allows for real-time optimization, ensuring that the machine frame remains isolated from harmful vibrations that could affect equipment performance or lifespan. The integration of harmonic filtering and active damping offers a comprehensive solution for managing mechanical vibrations, reducing wear and tear, and enhancing overall operational efficiency.
FIG. 2 illustrates sequential diagram of a vibration isolation system (100), in accordance with the embodiments of the pressent disclosure. The diagram illustrates the interactions within a vibration isolation system 100. The drive assembly 104 generates vibrations, which are then directed to the harmonic filter 102. The harmonic filter isolates predetermined vibration frequencies and sends the filtered vibrations back to the drive assembly 104, preventing transmission of excess vibrations. Remaining vibrations are transmitted to the machine frame 108, where they are absorbed by active dampers 106. The control unit 110 plays a central role, communicating with the active dampers 106 to adjust their operation based on detected harmonic interference, ensuring optimal damping. The active dampers 106 provide feedback to the machine frame 108 in the form of damping to control vibrational energy. Additionally, the control unit 110 interacts with the harmonic filter 102 to adjust filtering parameters, maintaining effective vibration isolation throughout the system. The sequence and flow ensure that vibrational impact is minimized, enhancing the overall stability and functionality of the machine.
In an embodiment, the vibration isolation system 100 achieves reduction in transmission of unwanted vibrational forces through the integration of a harmonic filter 102 within a drive assembly 104. The harmonic filter 102 isolates predetermined vibration frequencies, effectively reducing resonance and improving the operational stability of the drive assembly 104. By filtering out specific frequencies, the harmonic filter 102 prevents harmonic vibrations from propagating through the machine frame 108. Active dampers 106, which are strategically attached to the machine frame 108, absorb any residual vibrations that pass through the drive assembly 104. The control unit 110 communicates with both the harmonic filter 102 and the active dampers 106, adjusting the damping characteristics in response to detected harmonic interference. Such coordination among components provides real-time isolation and absorption of vibrations, minimizing oscillations that could negatively impact the machine's performance or longevity.
In an embodiment, the harmonic filter 102 is designed to filter vibration frequencies in the range of 50 Hz to 500 Hz, effectively reducing resonance effects during machine operation. The specific range targets frequencies most likely to induce resonance within the drive assembly 104 and surrounding structure. By filtering within this range, the harmonic filter 102 prevents the amplification of vibrational energy that occurs when natural frequencies of machine components coincide with operational frequencies. The selective filtering enables suppression of resonant vibrations that would otherwise lead to increased wear, potential damage, or operational inefficiency within the system. Such targeted filtering also aids in reducing noise levels and mechanical stress on the machine frame 108 and associated parts, improving overall machine performance.
In an embodiment, the drive assembly 104 includes a spindle rotationally mounted to interact directly with the harmonic filter 102. Said spindle, being a central component in generating rotational motion, is a primary source of vibrational frequencies, particularly at varying speeds or torque conditions. The interaction between the spindle and the harmonic filter 102 allows for the direct isolation of vibrational frequencies caused by rotational movement. This arrangement enables the harmonic filter 102 to effectively reduce vibrations at the source before they propagate to the machine frame 108. By controlling vibrations at the spindle level, the drive assembly 104 maintains more stable rotational movement, contributing to the overall stability and efficiency of the system.
In an embodiment, the active dampers 106 incorporate piezoelectric elements capable of dynamically adjusting damping force in response to the amplitude of detected harmonic vibrations. Piezoelectric elements offer the advantage of immediate response to varying vibrational intensities, allowing the active dampers 106 to change damping characteristics based on real-time data. As the amplitude of detected vibrations increases, the piezoelectric elements generate a proportional electrical signal, which is then used to modify the damping force applied by the active dampers 106. Such dynamic adjustment enhances the system's ability to minimize the transmission of vibrations across the machine frame 108 and prevents excessive oscillations that could compromise machine stability.
In an embodiment, the machine frame 108 is equipped with a sensor array positioned along its structural members to detect vibration intensity and provide feedback to the control unit 110. The sensor array continuously monitors various vibrational parameters, including amplitude, frequency, and direction of vibrations throughout the machine frame 108. By capturing this real-time data, the sensor array enables the control unit 110 to analyze the current vibrational state of the system and adjust the operation of the active dampers 106 accordingly. Such monitoring allows for more precise control of vibrational forces, improving the isolation and absorption of harmful vibrations, and maintaining the structural integrity of the machine frame 108.
In an embodiment, the control unit 110 comprises a processor and a memory module designed to calculate real-time vibration frequency data and manage the active dampers 106 based on such data. The processor receives input from the sensor array on the machine frame 108, analyzes the detected vibrational patterns, and generates control signals that are used to adjust the damping characteristics of the active dampers 106. The memory module stores relevant operational parameters, threshold values, and historical vibration data to facilitate rapid processing and accurate response to detected vibrations. Such a setup allows the control unit 110 to dynamically manage vibration isolation in the system, enhancing its effectiveness and adaptability.
In an embodiment, the active dampers 106 are strategically arranged at nodal points of the machine frame 108 to maximize vibration absorption efficiency. Nodal points are specific locations where vibrational amplitude is minimal, allowing the active dampers 106 to counteract vibrations more effectively. By placing active dampers 106 at these nodal points, the system can minimize the propagation of vibrations through the machine frame 108, reducing overall vibrational energy and increasing the stability of the structure. Such placement enhances the damping effect without requiring additional force or energy, leveraging the natural vibrational behavior of the frame.
In an embodiment, the harmonic filter 102 is capable of adjusting its frequency filtering parameters based on input from the sensor array on the machine frame 108, thereby continuously optimizing vibration isolation. The sensor array detects real-time vibrational conditions, and the control unit 110 uses this data to direct the harmonic filter 102 to alter its filtering characteristics, such as adjusting the frequency range or damping level. This continuous adaptation allows the system to respond to varying operational conditions and vibration sources, maintaining optimal isolation and minimizing the impact of harmonic vibrations throughout the machine's operational life.
In an embodiment, the control unit 110 further includes a user interface allowing for manual adjustments to both the harmonic filter 102 and the active dampers 106. Such a user interface enables an operator to input custom parameters, such as preferred vibration frequency ranges for filtering or desired damping levels for the active dampers 106. The user interface may provide real-time feedback on system performance, including current vibration levels and operational status of the components. This manual control feature allows for greater flexibility in adjusting the vibration isolation system 100 based on specific operational needs or environmental conditions.
In an embodiment, the machine frame 108 integrates a vibration suppression layer within its structural members to further reduce the transmission of vibrations across the frame. Said vibration suppression layer may consist of materials that exhibit high damping properties, such as elastomers, foams, or composites. The layer acts as a barrier to vibrational energy, absorbing and dissipating vibrations that would otherwise travel through the frame and reach sensitive components or external structures. This additional damping reduces noise, improves the comfort of machine operation, and extends the lifespan of the machine by minimizing vibrational stress on the frame.
Further, while operations are depicted in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrate
