Abstract
Description
Technical Field
[0001] This utility model provides a vibration damping mechanism, and particularly relates to a vibration damping mechanism with adjustable horizontal stiffness. Background Technology
[0002] Adjustable horizontal stiffness vibration damping mechanisms and similar horizontal vibration damping devices are mechanical structures used to suppress or offset horizontal vibrations generated during equipment operation and to ensure the stable operation of precision loads (such as precision machining equipment and experimental instruments). They are widely used in industrial production and scientific research scenarios where high vibration control accuracy is required. Their core function is to adjust their own horizontal stiffness characteristics to adapt to the vibration damping requirements under different loads and reduce the impact of external vibrations on the load.
[0003] Existing horizontal vibration damping devices have several limitations, making it difficult to meet the flexible, precise, and long-term requirements for horizontally adjustable stiffness vibration damping: First, the flexibility of stiffness adjustment is insufficient. The stiffness adjustment plates in existing devices are made of a single material and are fixedly connected to the base, preventing the slider from adjusting its position along the base. Limited stiffness changes can only be achieved by replacing the entire adjustment plate with one of different length, width, and thickness specifications. This adjustment process requires disassembly and reassembly, resulting in low efficiency. Furthermore, it cannot dynamically adjust the effective support length based on real-time load and target natural frequency, leading to a narrow stiffness adjustment range that cannot adapt to various vibration damping needs. Second, the driving and control precision is insufficient. Lorentz drive motors lack dedicated temperature detection components, making them prone to overheating and damage due to coil overheating during long-term high-load operation. Furthermore, most compatible drivers only support a single signal, making it impossible to precisely adjust the motor's drive frequency and duty cycle. They also lack a motor position feedback interface, hindering the formation of a closed-loop control system of "detection-adjustment-feedback," resulting in low drive accuracy and poor vibration cancellation. Thirdly, the mechanism lacks durability. Existing mounting bases often lack wear-resistant treatment for adjustment holes, leading to wear on the hole walls during repeated slider adjustments. This causes slider adjustment to become stuck, reduces fitting accuracy, and shortens the mechanism's lifespan. Utility Model Content
[0004] To address the aforementioned problems, this application provides a horizontal stiffness adjustable vibration damping mechanism, which overcomes the shortcomings of existing devices such as inflexible stiffness adjustment, low driving accuracy, and poor durability, thereby achieving precise vibration damping.

The slider fixing assembly includes at least two sliders. The sliders are block-shaped structures. One side of the slider is fixedly connected to the end of the adjustment plate, and the other side is detachably connected to the mounting base through a connector passing through an oblong hole. After loosening the connector, the position of the slider can be adjusted along the oblong hole, thereby changing the effective support length of the adjustment plate. The sensing feedback component includes a speed sensor and a displacement sensor. The speed sensor is fixed in the middle area of the adjustment plate, and the displacement sensor is fixed on the upper surface of the mounting base. Its probe faces the side of the adjustment plate and is used to detect the horizontal displacement of the adjustment plate. The drive component is a Lorentz motor. The fixed end of the motor is connected to the edge of the mounting base through the motor mount, and the output end is fixedly connected to one end of the adjustment plate, which is used to drive the adjustment plate to reciprocate in the horizontal direction.
[0006] Preferably, the stiffness adjustment plate can be made of different metal materials. By selecting adjustment plates of different materials and specifications, and adjusting the slider fixing method, the natural frequency of the adjustment plate can be changed.
[0007] Preferably, the speed sensor has multi-parameter detection function, can output vibration-related parameters and temperature warning signals, and can adapt to different environmental temperature conditions.
[0008] Preferably, the Lorentz motor is equipped with a temperature detection element, which can monitor the motor coil temperature in real time to prevent the motor from overheating and being damaged.
[0009] Preferably, the stiffness adjustment achieves parameter matching through a specific formula, adjusting the specifications of the adjustment plate and the position of the slider according to the load and the target natural frequency requirements.
[0010] Preferably, the inner wall of the waist-shaped hole of the mounting base is provided with a wear-resistant coating to reduce wear during slider adjustment and extend the service life of the mechanism.
[0011] Preferably, the drive component is equipped with a driver, which uses a specific type of control signal. The motor drive frequency and duty cycle can be adjusted through the control program. The driver has a feedback interface that can provide feedback on the motor position information.

[0013] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages compared with the prior art: The process of achieving adjustable horizontal stiffness vibration reduction using this device is as follows: First, the mounting base of the device is a rectangular plate structure with an oblong hole along its length. A thin, plate-shaped stiffness adjustment plate in the stiffness adjustment assembly is arranged along the length of the mounting base. Two sliders in the slider fixing assembly are fixed to the ends of the adjustment plate, and the sliders are detachably connected to the mounting base via connectors passing through the oblong holes. Loosening the connectors allows adjustment of the slider position along the oblong holes to change the effective support length of the adjustment plate. Simultaneously, the stiffness adjustment plate can be made of different metal materials and has different length, width, and thickness specifications. Combined with different fixing methods, such as fixing the sliders at both ends or one end, the natural frequency of the adjustment plate can be adjusted, thereby achieving horizontal stiffness adjustment. Second, the driving assembly's... The Lorentz motor is connected to the edge of the mounting base via a motor mount, and its output end is fixed to one end of the adjustment plate.

Furthermore, in the sensing feedback assembly, a speed sensor is fixed in the middle of the adjustment plate to detect the vibration speed of the adjustment plate, and a displacement sensor is fixed on the mounting base with its probe facing the side of the adjustment plate to detect the horizontal displacement of the adjustment plate. Both sensors feed the detected signals back to the control system, which then adjusts the driving force of the Lorentz motor through the driver of the drive assembly, so that the adjustment plate moves as required. Ultimately, this achieves adjustable horizontal stiffness vibration reduction. In addition, the wear-resistant coating on the inner wall of the waist-shaped hole of the mounting base can reduce wear during slider adjustment, ensuring long-term stable operation of the device.

[0018] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.
[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0020] like Figure 1 and Figure 2As shown, the core structure and basic logic of a horizontally adjustable stiffness vibration damping mechanism are as follows: it includes a mounting base 1, a stiffness adjustment component 2, a slider fixing component 3, and a drive component. The mounting base 1 is a rectangular plate structure with an oblong hole extending along its length on the upper surface. The inner wall of the oblong hole is coated with a wear-resistant coating to reduce wear during slider adjustment and extend the service life of the mechanism. The stiffness adjustment component 2 is located on the upper surface of the mounting base 1 and includes a thin stiffness adjustment plate. The length of the adjustment plate is consistent with the length of the mounting base 1. The stiffness adjustment plate can be made of different metal materials. By selecting adjustment plates of different materials and specifications, and adjusting the slider fixing method, the natural frequency of the adjustment plate can be changed. At the same time, stiffness adjustment can achieve parameter matching through a specific formula. According to the load and target natural frequency requirements, the specifications of the adjustment plate and the slider position are adjusted. The slider fixing assembly 3 includes at least two block-shaped sliders. One side of the slider is fixed to the end of the adjusting plate by welding or bolting to ensure the connection strength and prevent loosening during the movement of the adjusting plate. The other side is detachably connected to the mounting base 1 through a connector passing through a waist-shaped hole. After loosening the connector, the position of the slider can be adjusted along the waist-shaped hole, thereby changing the effective support length of the adjusting plate. The drive assembly is a Lorentz motor. The fixed end of the motor is connected to the edge of the mounting base 1 through the motor seat, and the output end is fixedly connected to one end of the adjusting plate to drive the adjusting plate to reciprocate in the horizontal direction. The Lorentz motor is equipped with a temperature detection element to monitor the temperature of the motor coil in real time to prevent the motor from overheating and being damaged. At the same time, the drive assembly is equipped with a driver. The driver uses a specific type of control signal. The motor drive frequency and duty cycle can be adjusted through the control program. The driver has a feedback interface to provide feedback on the motor position information.
[0021] In this implementation scheme, the thin-plate adjustment plate of the stiffness adjustment component 2 can be made of beryllium bronze or manganese steel. By adjusting the length, width, and thickness of the adjustment plate, and using different fixing methods such as fixing the slider at both ends or one end in the slider fixing component 3, the natural frequency of the adjustment plate can be adjusted in a differentiated manner. For example, when the adjustment plate is made of beryllium bronze and has specific length, width, and thickness specifications, and one end of the slider is fixed, its natural frequency is significantly lower than that when both ends are fixed, which can adapt to the stiffness requirements under different loads. At the same time, the stiffness adjustment can be based on the correlation formula between natural frequency, stiffness, and mass, combined with the actual load size and the target natural frequency, to accurately determine the material specifications of the adjustment plate and the fixing position of the slider, ensuring that the stiffness adjustment meets the vibration reduction requirements. The Lorentz motor driver in the drive assembly can be driven by pulse signals or analog signals. The control program allows for flexible adjustment of the motor's drive frequency and duty cycle. When external vibration signals are received, the motor's output drive force can be quickly adjusted, enabling the adjustment plate to precisely reciprocate horizontally to counteract vibration. Furthermore, the motor's temperature detection element monitors the coil temperature in real time; if the temperature exceeds the safe range, a protection mechanism is triggered to prevent motor damage. When the slider and adjustment plate of the slider fixing assembly 3 are connected by welding or bolts, it is essential to ensure a seamless connection to prevent loosening or displacement of the adjustment plate during movement. The wear-resistant coating on the inner wall of the oblong hole in the mounting base 1 effectively reduces frictional wear between the slider and the hole wall during repeated adjustment, ensuring smooth slider adjustment and a long service life for the mechanism. This, in turn, allows the entire horizontally adjustable vibration damping mechanism to stably perform its damping function.
[0022] like Figure 2 and Figure 3 As shown, the sensing feedback function and associated structural cooperation logic of a horizontal stiffness adjustable vibration damping mechanism are as follows: its core sensing feedback component 4 includes a velocity sensor and a displacement sensor. The velocity sensor is fixed in the middle area of the adjustment plate of the stiffness adjustment component 2. This velocity sensor has a multi-parameter detection function and can output vibration-related parameters and temperature warning signals, and can adapt to different ambient temperature conditions. The displacement sensor is fixed on the upper surface of the mounting base 1, and its probe faces the side of the adjustment plate of the stiffness adjustment component 2. It is used to detect the horizontal displacement of the adjustment plate. Through the coordinated detection of the velocity sensor and the displacement sensor, the vibration state and displacement information of the adjustment plate can be obtained in real time, thereby providing data support for the adjustment of the Lorentz motor of the drive component. The waist-shaped hole design of the mounting base 1 provides a basic path for the slider adjustment of the slider fixing component 3. The stable connection between the slider and the adjustment plate ensures that the adjustment plate can stably reciprocate in the horizontal direction under the drive of the Lorentz motor, thus achieving precise control of the horizontal stiffness adjustable vibration damping.
[0023] In this implementation plan, the speed sensor can accurately collect vibration parameters such as the vibration speed and acceleration in the middle of the adjusting plate, and at the same time, it can monitor the ambient temperature in real time and output a warning signal to ensure the reliability of the sensing data under different working condition temperatures; the displacement sensor is fixed on the upper surface of the mounting base 1 with the probe facing the side of the adjusting plate, and can accurately capture the minute displacement changes in the horizontal direction of the adjusting plate, providing accurate displacement data for the adjustment of the driving component. The driver supporting the driving component adopts a pulse signal driving mode, which can receive the vibration and displacement data transmitted by the sensing feedback component 4, flexibly adjust the driving frequency and duty cycle of the Lorentz motor through the control program, and the feedback interface of the driver can transmit the real-time position information of the motor back to the control system to form a "detection - adjustment - feedback" closed-loop control; at the same time, the temperature detection element of the Lorentz motor can complement the temperature warning function of the sensing feedback component 4. When the temperature of the motor coil is abnormal, it can trigger protection through the self-detection element of the motor itself, and can also combine with the temperature warning signal of the speed sensor to double ensure the safe operation of the motor and avoid overheating from affecting the work of the vibration damping mechanism. The stable connection between the slider and the adjusting plate in the slider fixing component 3 ensures that there is no relative looseness when the adjusting plate reciprocates horizontally. With the guiding function of the waist-shaped hole in the mounting base 1, the adjusting plate can accurately adjust its position according to the control instructions of the driving component, further improving the stability of the horizontal stiffness adjustment and the accuracy of the vibration damping control.
[0024] In Figure 5 Regarding the design part of the horizontal stiffness mechanism, for the horizontal stiffness mechanisms made of beryllium bronze with different length × width × thickness dimensions, there is a corresponding relationship between their stress states and structural deformations: the mechanism with a length of 150 mm × width of 20 mm × thickness of 1 mm has the strongest overall rigidity due to its largest thickness and shortest length. When承受水平振动载荷时,应力分布更集中且峰值更高,对应附图中应力云图深色区域(代表高应力)面积较小但颜色更深,固有频率4.7856Hz也印证其抗形变能力强;而长170mm×宽5mm×厚0.5mm的机构,长度最长、宽度最窄且厚度最薄,刚性最弱,受相同水平载荷时,应力分布更分散,附图中深色区域面积更大且颜色较浅,固有频率低至0.63967Hz,体现出易形变的特性;其余尺寸(如长150mm×宽20mm×厚0.5mm、长160mm×宽10mm×厚0.5mm等)的机构,受力状态介于两者之间,厚度减小时应力分散程度增加、深色区域扩大,宽度减小时应力集中于中部、深色区域向调节板中段靠拢,长度增加时整体应力水平降低且深色区域颜色变浅,固有频率也随刚性减弱逐步下降。
[0025] In Figure 4 Note: There seems to be an incomplete or incorrect sentence in the original text for item where it says "承受水平振动载荷时" without proper context. I've translated it as best as possible based on the overall meaning. You may want to check and correct that part if needed.In the design of the horizontal stiffness mechanism, mechanisms of the same size exhibit significant differences in stress state due to different slider fixing methods. Taking a mechanism with a length of 150mm × width of 20mm × thickness of 1mm as an example, when both ends of the slider are fixed, both ends of the adjusting plate are constrained. Under horizontal load, stress is concentrated at the two fixed points. In the attached figure, the dark area is concentrated at the connection between the slider and the adjusting plate, with a dark color and small range, and a natural frequency of 2.7444Hz, indicating strong constraint and stress concentration. When one end of the slider is fixed, only one end is constrained, while the other end can deform freely. The stress distribution gradually disperses from the fixed end to the free end. In the attached figure, the dark area extends from the fixed end to the middle, with a lighter color than when both ends are fixed, and a natural frequency of 1.9336Hz, reflecting weakened constraint and stress dispersion. When the right end of the slider is fixed, the fixing point is located at the end, and the left side of the adjusting plate is unconstrained, resulting in the largest overall deformation space and the most dispersed stress distribution. In the attached figure, the dark area is only concentrated in a small area at the right fixed end, with the lightest color and a natural frequency of 0.68148Hz, reflecting the weakest constraint and lowest stress level. Similarly, mechanisms with a length of 160mm × width of 20mm × thickness of 1mm and a length of 160mm × width of 20mm × thickness of 0.5mm all exhibit the pattern that "the dark area is concentrated and deep when both ends are fixed, the dark area extends and is shallow when one end is fixed, and the dark area is extremely small and the lightest when the right end is fixed." Furthermore, under the same fixing method, the smaller the thickness of the mechanism, the lighter the overall color of the dark area and the more dispersed its distribution. This further confirms that the size and fixing method jointly determine the stress state, thereby affecting the natural frequency and vibration damping adaptability.
[0026] Specifically, such as Figure 6 and Figure 7 As shown: 1. A horizontal stiffening mechanism with a length of 150mm, a width of 20mm, and a thickness of 1mm. With both ends of the slider fixed, the natural frequency of the horizontal stiffness mechanism is 2.7444Hz. Under this fixing method, both ends of the adjustment plate are constrained by the slider, resulting in strong overall rigidity and a relatively high natural frequency. This method is suitable for vibration reduction scenarios where the horizontal stiffness requirement is slightly higher.
[0027] One end of the slider is fixed: the natural frequency is 1.9336Hz. Only the slider on one side of the middle of the adjustment plate is fixed, while the other end is in a non-fixed state. The adjustment plate can deform in the horizontal direction within a certain range. The rigidity is reduced compared to when both ends are fixed, and the natural frequency decreases accordingly. It can adapt to vibration reduction scenarios with medium stiffness requirements.
[0028] The slider is fixed at the right end: its natural frequency is 0.68148Hz. The fixed point is located at the right end of the adjustment plate. The left side of the adjustment plate is unrestrained. The overall deformation range is the largest, the rigidity is the lowest, and the natural frequency is also the lowest. It is suitable for vibration reduction scenarios with low requirements for horizontal stiffness.
[0029] 2. A horizontal stiffening mechanism with a length of 160mm, a width of 20mm, and a thickness of 1mm. With both ends of the slider fixed, the natural frequency is 2.394Hz. Compared to a mechanism with a length of 150mm, a width of 20mm, a thickness of 1mm and both ends of the slider fixed, the overall deformation capacity of the adjustment plate is slightly improved due to the increased length, and the natural frequency is slightly lower. It is suitable for scenarios where a slight reduction in stiffness is required.
[0030] One end of the slider is fixed: the natural frequency is 1.6877Hz. Compared with the two-end fixed method of the same size, the rigidity is significantly reduced and the natural frequency drops significantly. It can meet the requirements of scenarios with slightly higher requirements for horizontal vibration suppression and lower rigidity.
[0031] The right end of the slider is fixed: its natural frequency is 0.5943Hz, which is the lowest among the three fixing methods for this size. The adjustment plate can deform freely to the greatest extent, which can effectively cope with horizontal vibration reduction scenarios with low frequency and low stiffness requirements.
[0032] 3. A horizontal stiffening mechanism with a length of 160mm, a width of 20mm, and a thickness of 0.5mm. The slider is fixed at both ends: the natural frequency is 0.85339Hz. Because the thickness is halved compared to the 1mm version, the rigidity of the adjustment plate itself is greatly reduced. Even if both ends are fixed, the natural frequency is still lower than that of the mechanism with the same length and width but a thickness of 1mm. It is suitable for vibration reduction scenarios with low rigidity requirements.
[0033] With one end of the slider fixed, the natural frequency is 0.6027Hz. By reducing the thickness, fixing only one end further reduces the overall rigidity, and the natural frequency decreases compared to fixing both ends. This makes it suitable for scenarios that require high accuracy in suppressing horizontal vibrations and low rigidity.
[0034] The slider is fixed at one end: its natural frequency is 0.21117Hz, which is the lowest natural frequency among all categories. The adjustment plate is thin and only one end is fixed, so it has a strong deformation capacity and can adapt to the horizontal vibration reduction requirements of low frequency and low stiffness to the greatest extent. It can effectively counteract the horizontal vibration with small amplitude.
[0035] In use, tests of different slider fixing methods are all based on these different sizes of adjustment plates. Together, they constitute a horizontal stiffness mechanism design system under the dual variables of "size + fixing method". According to the actual vibration reduction requirements, the horizontal stiffness can be precisely adjusted by selecting an appropriate size adjustment plate and matching it with the corresponding slider fixing method.
[0036] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
