Description

Technical Field

[0001] This invention relates to the field of vibration isolation devices, and more specifically, to a capsule vibration isolation system capable of wave field reshaping. Background Technology

[0002] With the gradual improvement of urban construction and the accelerated development of urban clusters, traditional road transportation can no longer meet people's needs. The mileage of rail transit such as high-speed trains and subways has increased significantly, making vibration a problem that cannot be ignored. Furthermore, with the increase in population and building density, the vibration hazards generated by the operation of various heavy industrial equipment are also increasing. Vibration can pose structural safety hazards to buildings and cause serious consequences such as reduced lifespan and excessive error range for high-precision equipment. In addition, vibration also has a significant impact on human comfort.

[0003] However, vibration reduction and isolation methods all have inherent drawbacks or are not suitable for the current development trends of buildings and population density, which lead to a reduction in the space available for vibration isolation. Vibration reduction methods based on vibration sources will increase the cost of track construction and reduce the energy efficiency of vibration source plants; in vibration reduction methods based on propagation paths, vibration reduction trenches are prone to collapse, and ground retaining walls are not very effective; moreover, the current environment has a complex vibration source background, making it difficult for vibration isolation methods to effectively isolate various forms of vibration waves.

[0025] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention. In the following detailed description, numerous specific details are set forth to provide a thorough understanding of the embodiments of the invention for ease of explanation. However, it will be apparent that one or more embodiments may be practiced without these specific details. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0026] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0027] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.

[0028] When using expressions such as "at least one of A, B and C", they should generally be interpreted in accordance with the meaning that is commonly understood by those skilled in the art (e.g., "a system having at least one of A, B and C" should include, but is not limited to, a system having A alone, a system having B alone, a system having C alone, a system having A and B, a system having A and C, a system having B and C, and / or a system having A, B and C, etc.).

[0029] With the rapid development of urban clusters, the operation of various industrial equipment generates a large amount of complex background noise based on different vibration sources. However, vibration reduction and isolation methods are relatively simple and cannot effectively isolate the various complex background noises generated in the above situations. Considering that short-wavelength elastic waves are easier to block than long-wavelength elastic waves, it is conceivable to reshape the wave field of elastic waves to transform the difficult-to-block long-wavelength high-energy elastic waves into easily blocked short-wavelength low-energy elastic waves, and then perform efficient vibration isolation treatment on the short-wavelength low-energy elastic waves. At the same time, it is also necessary to consider buffering elastic waves with high instantaneous impact energy, such as explosions, to ensure the stability of the system. Based on this, this invention proposes a capsule vibration isolation system that can realize wave field reshaping, which includes an interference module for buffering, a wave-shaping module for realizing wave field reshaping, and a vibration isolation module for realizing vibration isolation treatment.

[0030] Figure 1 A schematic diagram of a capsule isolation system capable of wave field reshaping according to an embodiment of the present invention is shown.

[0031] like Figure 1 As shown, the wave field reshaping-enabled capsule vibration isolation system according to this embodiment includes an interference module 101, a wave shaping module 102, and a vibration isolation module 103.

[0032] The interference module 101 includes at least one interference capsule, which is configured to buffer the elastic wave generated by the vibration source to obtain a first elastic wave.

[0033] Buffering elastic waves can be achieved by altering their spatiotemporal characteristics through a series of means, reducing their peak stress or acceleration, extending their duration, and dissipating their energy, thereby protecting the target module.

[0034] Methods for buffering elastic waves include, but are not limited to, energy dissipation, energy redistribution, energy storage and release, and energy reflection and isolation. Energy dissipation refers to the irreversible conversion of the mechanical energy of the impact into other forms; energy redistribution refers to the spatial dispersion of concentrated, instantaneous energy over a larger area or its temporal extension; energy storage and release refers to the temporary storage of energy in the form of elastic potential energy, followed by its slow release in a non-destructive manner; and energy reflection and isolation refers to preventing the impact energy from entering the protected area.

[0035] For example, based on buffer energy-absorbing structures, pre-designed geometries (such as honeycomb, corrugated plates, and tapered tubes) can undergo controllable, gradual folding, buckling, or tearing under axial impact, stably absorbing energy through large deformation of the structure.

[0036] The wave-shaping module 102 includes at least one wave-shaping capsule, which is farther away from the vibration source than the interference capsule. The wave-shaping capsule is configured to reshape the wave field of the first elastic wave to obtain a second elastic wave.

[0037] The fact that the wave-forming capsule is farther from the vibration source than the interference capsule means that the positional relationship between the wave-forming capsule and the interference capsule needs to ensure that the elastic wave is first buffered by the interference capsule and then reshaped by the wave-forming capsule.

[0038] Wavefield reshaping can be achieved through active or passive physical methods, altering wave propagation paths, energy distribution, phase, and other related parameters in space. Methods for reshaping wavefields include, but are not limited to: altering the material parameters of the wave-forming capsule to influence wave velocity through the design of the material's spatial distribution, thereby controlling refraction, reflection, and propagation paths; introducing boundaries and utilizing boundary conditions (such as free boundaries, fixed boundaries, and impedance boundaries) to reflect, convert, or guide waves; applying external excitation and directly synthesizing the target wavefield by controlling the temporal and spatial characteristics of the excitation source; and utilizing time-varying or nonlinear effects to make material parameters or boundary conditions change over time, or utilizing the nonlinear interactions of waves.

[0039] The vibration isolation module 103 includes at least one vibration isolation bladder, which is farther away from the vibration source than the plastic wave bladder, and is configured to isolate the second elastic wave.

[0040] The vibration isolation capsule is farther away from the vibration source than the wave-forming capsule. This means that the positional relationship between the vibration isolation capsule and the wave-forming capsule needs to ensure that the elastic wave is first buffered by the wave-forming capsule and then isolated by the vibration isolation capsule.

[0041] Vibration isolation of elastic waves can be achieved through passive isolation relying on the inherent physical properties of the isolation chamber itself, or through active isolation by introducing sensors, controllers, and actuators to achieve real-time dynamic control. For example, in passive isolation, an inertial block can be placed inside the isolation chamber to reduce its sway and distribute the load evenly. In active isolation, accelerometers or displacement sensors can be installed on the isolation chamber to measure residual vibration in real time. The controller calculates a cancellation signal, driving the actuator to generate a reaction force that directly cancels out the vibration.

[0042] For any of the following types of capsules—interference capsules, wave-forming capsules, and vibration-isolation capsules—the capsule can be a sealed container made of a flexible, high-strength rubber composite material, filled with compressible gas. The gas pressure inside the capsule can be adjusted; by adjusting the gas pressure, the capsule can withstand loads ranging from hundreds of kilograms to tens of tons, with the load-bearing capacity directly proportional to the gas pressure. Simultaneously, by adjusting the gas pressure, the stiffness of the capsule can be controlled, and based on this stiffness control, different responses to elastic waves can be achieved.

[0043] For any type of bladder, including interference bladders, wave-forming bladders, and vibration isolation bladders, the number of bladders, the number of rows of bladders, and the size of bladders can be determined according to the area occupied by the vibration source or the protected object and the engineering requirements, and the arrangement of the bladders can be freely selected.

[0044] For any of the following types of capsules—interference capsules, wave-forming capsules, and vibration-isolation capsules—the capsule can be buried in the soil or placed on the ground. The process of burying the capsule in the soil can be done either by burying an empty capsule or by burying it with pre-inflated air, depending on the soil conditions. However, regardless of the method, the quality and airtightness of the capsule must be checked. The pre-inflation pressure and final air pressure of the capsule should be determined comprehensively based on the soil properties, the magnitude of the soil pressure at the deepest point, and the capsule material.

[0045] Through the embodiments of the present invention, elastic waves can be blocked based on multiple vibration isolation mechanisms, transforming the traditional single method of reflecting elastic waves into a combined vibration isolation method with multiple bladders and multiple mechanisms. Furthermore, due to the high freedom and flexibility of the bladders, it is easier to meet the vibration reduction design requirements of different vibration sources and protected objects, thereby improving the vibration isolation efficiency in different vibration isolation scenarios.

[0046] Figure 2 A schematic diagram of an interference module according to an embodiment of the present invention is shown.

[0047] like Figure 2 As shown, the interference module includes an interference capsule 200 and polymer particles 201.

[0048] The interference capsule 200 is filled with gas and polymer particles 201. The polymer particles 201 are configured to dissipate the impact energy of elastic waves generated by the vibration source based on friction and collision, thereby buffering the elastic waves generated by the vibration source. In embodiments of the present invention, the gas content and polymer particle 201 content inside the interference capsule 200 can be configured as needed, and the configured interference capsule is sealed to buffer elastic waves.

[0049] The gas can be air, and the types of polymer particles 201 include, but are not limited to: natural rubber particles, polyurethane foam particles, polyethylene foam particles, polyolefin particles, polystyrene beads, magnetorheological elastomer particles, etc.

[0050] In embodiments of the present invention, the shape, size, surface roughness, particle size distribution and filling rate of the polymer particles 201 can be selected according to engineering needs to achieve better elastic wave buffering.

[0051] Through the embodiments of the present invention, elastic waves generated by vibration sources can be buffered to prevent the impact energy of elastic waves from damaging the vibration isolation system.

[0052] According to an embodiment of the present invention, the interference module may include: an air compressor and a plurality of second pneumatic valves, wherein the air compressor is connected to the plurality of second pneumatic valves respectively, and the second pneumatic valves are connected to the interference capsule; wherein the second pneumatic valves are configured to control the gas pressure inside the interference capsule during the process of the gas compressor inputting gas and polymer particles into the interference capsule, thereby forming polymer particles with different filling ratios, and the polymer particles with different filling ratios are configured to buffer the elastic waves generated by the vibration source.

[0053] Figure 3 A schematic diagram of an interference module according to another embodiment of the present invention is shown.

[0054] like Figure 3 As shown, the interference module includes an air compressor 310, a first air pressure stabilizer 320, an anti-backflow mesh 330, a first pneumatic main valve 340, a polymer pulverizer 350, a first and second pneumatic valves 361, a second and third pneumatic valves 362, a third and fourth pneumatic valve 363, a first interference capsule 371, a second interference capsule 372, and a third interference capsule 373.

[0055] Air compressor 310 serves to fill the gas chamber and is connected to polymer pulverizer 350 via a flexible conduit. Polymer pulverizer 350 pulverizes polymer foam and uses the airflow from air compressor 310 to fill the interference chamber with polymer particles, increasing its support for the sidewall soil. First pressure stabilizer 320, anti-backflow net 330, and first pneumatic master valve 340 are fixed at the flexible conduit between air compressor 310 and polymer pulverizer 350. First pressure stabilizer 320 stabilizes the gas pressure within the interference chamber; first pneumatic master valve 340 controls the overall air pressure and provides safety protection by stopping pressurization in case of emergency; anti-backflow net 330 prevents polymer particles from flowing back into air compressor 310 and clogging it. The polymer pulverizer 350 is connected to the first interference capsule 371, the second interference capsule 372 and the third interference capsule 373 through a flexible conduit. The first and second pneumatic valves 361 control the gas pressure of the first interference capsule 371, the second and second pneumatic valves 362 control the gas pressure of the second interference capsule 372 and the third and second pneumatic valves 363 control the gas pressure of the third interference capsule 373.

[0056] The first interference capsule 371, the second interference capsule 372, and the third interference capsule 373 can form polymer particles with different filling ratios, thereby providing different degrees of buffering for the elastic waves generated by the vibration source.

[0057] Through the embodiments of the present invention, the gas pressure inside the interference capsule can be controlled in real time, and polymer particles with different filling ratios can be formed as needed, thereby enabling more precise elastic wave buffering.

[0058] According to an embodiment of the present invention, the wave capsule includes: at least one magnet configured to be fixedly disposed on the inner surface of the wave capsule; and a magnetic pendulum configured to be fixedly disposed on a suspension by a non-metallic chain, the suspension being fixed inside the wave capsule; wherein, the at least one magnet is configured to generate a magnetic field under the control of a far-infrared control signal; the magnetic pendulum is configured to oscillate based on a target frequency under the action of the magnetic field, and is configured to modulate the target frequency band of a first elastic wave based on the oscillation frequency, change the resonance peak of the first elastic wave based on the oscillation damping, and change the phase of the first elastic wave based on the oscillation angle, so as to reshape the wave field of the first elastic wave.

[0059] In embodiments of the present invention, a far-infrared signal receiver, such as a far-infrared photoelectric sensor, can be integrated onto the magnet. An external controller transmits an encoded far-infrared control signal wirelessly to the magnet's far-infrared signal receiver. The receiver decodes the encoded far-infrared control signal and converts it into electrical commands. These electrical commands control the on / off state of the microcircuit inside the magnet, thereby controlling the coil current of the electromagnet and altering the magnetic field strength and equivalent dynamic parameters, thus generating a preset magnetic field effect.

[0060] In embodiments of the present invention, the oscillation frequency of the magnetic pendulum can be changed by altering the direction of the magnetic field. For example, by controlling the magnetic field to undergo 50 left-right directional changes within one second using a far-infrared control signal, the magnetic pendulum oscillates left and right 50 times within one second, thereby controlling the magnetic pendulum to oscillate at a frequency of 50 Hz. By adjusting the duration of the magnetic field's action, the phase difference between the magnetic pendulum and the elastic wave can be altered. Due to the out-of-phase vibration of the magnetic pendulum and the elastic wave, the damping of the interference capsule relative to the elastic wave is constantly adjusted in real time. Increasing the damping blunts the resonance peak of the elastic wave, while decreasing the damping makes the resonance peak sharper. A sharper resonance peak leads to stronger phase abrupt changes and scattering. Simultaneously, by strengthening the current, the magnetic force of the magnetic field on the magnetic pendulum can be increased, thereby changing the oscillation angle of the magnetic pendulum. When the oscillation angle of the magnetic pendulum is large, the elastic wave exhibits frequency doubling / division.

[0061] Through the embodiments of the present invention, precise elastic wave field reshaping can be achieved based on a magnetic pendulum, which helps to achieve highly flexible vibration isolation.

[0062] Figure 4 A schematic diagram of a wave-shaping module according to an embodiment of the present invention is shown.

[0063] like Figure 4 As shown, the wave-forming module includes a wave-forming capsule 400, a suspension 401, a magnet 402, and a magnetic pendulum 403.

[0064] The suspension 401 is fixed inside the plastic wave capsule 400. The magnetic pendulum 403 is connected to the suspension 401. The magnet 402 is fixed on the inner side of the plastic wave capsule 400. Under the control of the far-infrared control signal, the magnet 402 generates a magnetic field, thereby driving the magnetic pendulum 403 to swing based on the target frequency in order to reshape the wave field of the elastic wave.

[0065] The wave-forming capsule 400 can be filled with an inert gas. The inert gas content inside the wave-forming capsule 400 can be configured as needed. The configured wave-forming capsule is then sealed to form a gas spring. The gas spring is configured to dissipate the energy of the first elastic wave, thereby isolating the first elastic wave. The inert gas can be nitrogen, helium, or neon, etc., and its function is to prevent oxidation of the various devices inside the wave-forming capsule 400. In embodiments of the present invention, the inert gas can be a dry inert gas. The gas spring is an elastic element that uses a compressible gas as an energy storage medium. By pre-setting wave-forming capsules of different volumes and inert gas at different pressures, a low natural frequency can be achieved based on the compressibility of the gas, and damping control can be achieved through additional structures.

[0066] Through the embodiments of the present invention, the plastic wave module can also have a certain vibration isolation effect, thereby realizing the joint vibration isolation of multiple bladders and improving the vibration isolation efficiency.

[0067] According to an embodiment of the present invention, the wave-forming module may include: a gas compressor and a plurality of first pneumatic valves, wherein the gas compressor is connected to the plurality of first pneumatic valves respectively, and the first pneumatic valves are connected to the wave-forming chamber; wherein, the first pneumatic valves are configured to control the gas pressure inside the wave-forming chamber during the process of the gas compressor inputting inert gas into the wave-forming chamber, the wave-forming chamber and the inert gas at different pressures form gas springs of different stiffnesses, and the gas springs of different stiffnesses are configured to perform vibration isolation treatment on the first elastic wave.

[0068] In embodiments of the present invention, gas springs of different stiffness can be formed inside the plastic wave capsule based on inert gas at different pressures, thereby providing different degrees of vibration isolation for elastic waves.

[0069] Through the embodiments of the present invention, the gas pressure inside the plastic wave capsule can be controlled in real time, and gas springs with different stiffnesses can be formed as needed, thereby enabling more precise elastic wave vibration isolation treatment.

[0070] Figure 5 A schematic diagram of a wave-shaping module according to another embodiment of the present invention is shown.

[0071] like Figure 5 As shown, the wave-shaping module includes a gas compressor 510, a second pressure stabilizer 520, a second pneumatic master valve 530, a first pneumatic valve 541, a second first pneumatic valve 542, a third first pneumatic valve 543, a first wave-shaping capsule 551, a second wave-shaping capsule 552, a third wave-shaping capsule 553, a suspension 5511, a first oscillator 5512, a second oscillator 5513, a third oscillator 5514, a first magnet 5515, a second magnet 5516, and a third magnet 5517. The first wave-shaping capsule 551, the second wave-shaping capsule 552, and the third wave-shaping capsule 553 can be cylindrical capsules.

[0072] The gas compressor 510 can pressurize inert gas into the bladder, reducing the bladder's stiffness, increasing elastic wave attenuation, and preventing oxidation of the internal components. The gas compressor 510 is connected to the first plastic wave bladder 551, the second plastic wave bladder 552, and the third plastic wave bladder 553 via flexible conduits. The second pressure stabilizer 520 and the second pneumatic master valve 530 are fixed at the flexible conduits between the gas compressor 510 and the first, second, and third plastic wave bladders 551, 552, and 553. The second pressure stabilizer 520 stabilizes the gas pressure within the plastic wave bladder, and the second pneumatic master valve 530 provides overall pressure control and safety protection by stopping pressurization in case of emergency. The first pneumatic valve 541 controls the gas pressure of the first plastic wave bladder 551, the second pneumatic valve 542 controls the gas pressure of the second plastic wave bladder 552, and the third pneumatic valve 543 controls the gas pressure of the third plastic wave bladder 553.

[0073] The suspension 5511 is fixed inside the first plastic wave capsule 551, allowing inert gas to pass through. The first oscillator 5512, the second oscillator 5513, and the third oscillator 5514 form a magnetic pendulum. The first magnet 5515 is fixed below the suspension 5511. The first magnet 5515 and the first oscillator 5512, the first oscillator 5512 and the second oscillator 5513, and the second oscillator 5513 and the third oscillator 5514 are all connected by non-metallic chains. These non-metallic chains prevent the magnetic pendulum from failing due to the magnet generating magnetic force and attracting the non-metallic chains. The second magnet 5516 is fixed to the lower surface of the first plastic wave capsule 551, and the third magnet 5517 is fixed to the side surface of the first plastic wave capsule 551. The first magnet 5515 and the second magnet 5516 are arranged symmetrically along the axis of the columnar capsule. The magnetic force exerted by the first magnet 5515 and the second magnet 5516 on the magnetic pendulum is greater than that exerted by the third magnet 5517. The first magnet 5515, the second magnet 5516, and the third magnet 5517 can form a magnetic cage to provide external force for the magnetic pendulum composed of the first oscillator 5512, the second oscillator 5513, and the third oscillator 5514. A far-infrared control signal can be generated by a controller to control the first magnet 5515, the second magnet 5516, and the third magnet 5517 to generate different magnetic forces, causing the first oscillator 5512, the second oscillator 5513, and the third oscillator 5514 to oscillate, thereby dissipating the incident elastic wave and reshaping the wave field.

[0074] In embodiments of the present invention, the first oscillator 5512, the second oscillator 5513, and the third oscillator 5514 form a multi-degree-of-freedom oscillator system through coupled vibration, enabling the transfer and redistribution of elastic wave energy among multiple modes, thereby achieving coordinated control and wavefield reshaping of elastic waves in different frequency bands. The second oscillator 5513 is the master oscillator, and the first oscillator 5512 and the third oscillator 5514 are auxiliary oscillators. Based on the master and auxiliary oscillators, the system is a multi-degree-of-freedom system in dynamics, with multiple natural frequencies. The incident wave no longer excites a single resonance, but a combination of the primary mode and the secondary mode. The master and auxiliary oscillators cooperate to achieve energy transfer and internal resonance. When the master oscillator is excited, beat vibration, internal resonance, and energy cyclically transfer between different oscillators are formed. The vertically arranged auxiliary oscillators form a spatially symmetrical structure that suppresses system yaw and unidirectional instability, resulting in a more stable response to elastic waves incident from different directions or with different polarizations.

[0075] According to an embodiment of the present invention, the vibration isolation bladder is filled with a hydraulic cementitious material configured to impede the transmission of the second elastic wave, thereby isolating the second elastic wave.

[0078] The hydraulic cementitious material 601 can form rigid material blocks inside the vibration isolation cell 600. By pre-mixing different amounts of hydraulic cementitious material 601 inside the vibration isolation cell 600, rigid material blocks of different sizes can be formed inside the vibration isolation cell 600. The vibration isolation cell containing the rigid material blocks is then buried in the soil to isolate elastic waves. The hydraulic cementitious material includes, but is not limited to: general-purpose cement, special-purpose cement, fly ash, slag powder, silica fume, etc.

[0081] Figure 7 A schematic diagram of a vibration isolation module according to another embodiment of the present invention is shown.

[0082] like Figure 7 As shown, the vibration isolation module includes an air extraction pump 710, an air extraction main valve 720, a first air extraction valve 731, a second air extraction valve 732, a third air extraction valve 733, a first vibration isolation bladder 741, a second vibration isolation bladder 742, a third vibration isolation bladder 743, a first grouting valve 751, a second grouting valve 752, a third grouting valve 753, a grouting main valve 760, and a grouting pump 770.

[0083] A vacuum pump 710 is connected to the first vibration isolation bladder 741, the second vibration isolation bladder 742, and the third vibration isolation bladder 743 via a flexible gas conduit. It is used to extract gas from these bladders, allowing the hydraulic cementitious material to be smoothly injected into them. A main vacuum valve 720 controls the gas extraction from all vibration isolation bladders and provides emergency braking in case of danger. The first vacuum valve 731, the second vacuum valve 732, and the third vacuum valve 733 respectively control the vacuum pressure within the first vibration isolation bladder 741, the second vibration isolation bladder 742, and the third vibration isolation bladder 743, and can be quickly inserted and removed when needed. The grouting pump 770 is connected to the first vibration isolation bladder 741, the second vibration isolation bladder 742, and the third vibration isolation bladder 743 via a flexible grouting pipe. It is used to inject hydraulic cementitious material into the first vibration isolation bladder 741, the second vibration isolation bladder 742, and the third vibration isolation bladder 743. The grouting master valve 760 is used to control the pumping of hydraulic cementitious material into all vibration isolation bladders and to stop the pumping in case of danger. The first grouting valve 751, the second grouting valve 752, and the third grouting valve 753 control the injection speed of hydraulic cementitious material into the first vibration isolation bladder 741, the second vibration isolation bladder 742, and the third vibration isolation bladder 743, respectively, to form rigid material blocks of different specifications.

[0084] Through the embodiments of the present invention, the injection speed of the hydraulic cementitious material inside the vibration isolation bladder can be controlled in real time, and rigid material blocks of different specifications can be formed as needed, thereby enabling more precise elastic wave vibration isolation treatment.

[0085] According to an embodiment of the present invention, the bladder vibration isolation system further includes: a first wave characteristic sensor, which is closer to the vibration source than the plastic wave bladder, and is configured to acquire a first wave characteristic signal of a first elastic wave; a second wave characteristic sensor, which is farther from the vibration source than the vibration isolation bladder, and is configured to acquire a second wave characteristic signal of the elastic wave after processing by the vibration isolation module; and a controller, configured to receive the first wave characteristic signal and the second wave characteristic signal, and generate a far-infrared control signal based on the wave characteristic parameters of the first wave characteristic signal and / or the second wave characteristic signal.

[0086] The controller can adjust the vibration isolation system based on a first wave characteristic signal. For example, a sensor can acquire the target frequency of the elastic wave and generate a far-infrared control signal that causes the magnetic pendulum to swing based on that target frequency. The wave field of the elastic wave is reshaped by the resonance between the magnetic pendulum and the elastic wave at the same frequency. The controller can also adjust the output feedback of the vibration isolation system based on a second wave characteristic signal. For example, a sensor can acquire the frequency band energy information of the elastic wave and adjust the swing of the magnetic pendulum based on this information, allowing the pendulum to dissipate more frequency band energy. The controller can also precisely adjust the relevant parameters of the vibration isolation system based on a comprehensive analysis of the first and second wave characteristic signals.

[0087] In embodiments of the present invention, the wave characteristic parameters include, but are not limited to: displacement, velocity, acceleration, dominant frequency, amplitude, and frequency band energy. Sensors include, but are not limited to: piezoelectric accelerometers, inertial velocity sensors, strain gauges and force sensors, fiber Bragg grating sensors, and laser Doppler vibration meters.
