Description
Technical Field
[0001] This utility model relates to the field of structural vibration control technology, and in particular to a rope-type eddy current inertial capacitive damper. Background Technology
[0002] Traditional viscous damping devices suffer from significant drawbacks in practical engineering applications, including insufficient damping force, temperature sensitivity, high maintenance costs, and leakage. There is an urgent need to develop new, efficient vibration reduction and isolation technologies. In recent years, inertial capacitive elements have gained increasing attention as high-performance vibration control components. Their working principle involves amplifying inertial mass through a specific motion conversion mechanism, thereby achieving highly efficient structural vibration control with minimal physical mass.
[0003] Compared to traditional vibration reduction systems, inertial capacitance vibration reduction systems not only amplify apparent mass and enhance damping energy dissipation, but also offer advantages such as lightweight design and negative stiffness. However, from a mechanical perspective, typical inertial capacitance elements exhibit conservative characteristics, with their function primarily limited to energy absorption and short-term storage. Therefore, their vibration reduction effect needs improvement. To achieve more diverse vibration control objectives, inertial capacitance elements need to be combined with other mechanical units to construct a complete energy transfer, absorption, and dissipation path, thereby enhancing the vibration reduction performance. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a rope-type eddy current inertial capacitive damper that combines inertial capacitive damping, eddy current damping, self-resetting, and encapsulation technologies. Through energy conversion and regulation mechanisms, it improves vibration reduction performance.
[0005] To achieve the above objectives, the present invention adopts the following technical solution.
[0006] A rope-type eddy current inertial capacitive damper includes:
[0007] The shell is a cavity structure;
[0008] An eddy current inertial capacitance unit is disposed within the housing, including an inner cylinder, a ball screw, and a damping unit;
[0009] The bottom of the inner cylinder is fixedly connected to an inner end face of the shell;
[0010] One end of the ball screw is connected to a ball nut fixed to the bottom of the inner cylinder, and a safety clearance is maintained between the end and the bottom of the inner cylinder; the other end of the ball screw is rotatably connected to the other inner end face of the housing.
[0011] The damping unit is disposed between the inner cylinder and the ball screw, and includes an inertial flywheel and a magnetic component arranged in an alternating manner. The inertial flywheel is mounted on the ball screw, and the magnetic component is mounted on the inner wall of the inner cylinder.
[0012] An elastic reset element is disposed inside the housing, and its two ends are respectively connected to the two ends of the housing.
[0013] The damper comprises an inner cylinder, ball screw, ball nut, and an inertial flywheel mounted on the ball screw, forming an inertial capacitive system; an inertial flywheel and magnetic components, forming an eddy current damping system; an elastic reset component, forming a reset system; and a housing, forming an encapsulation system. During implementation, the damper is installed in a pre-defined scenario using lifting lugs and ropes. When relative displacement occurs at both ends of the housing, the inertial capacitive system converts linear motion into rotational motion of the inertial flywheel, generating an inertial force on the flywheel that is much greater than its physical mass. Simultaneously, a Lorentz force opposite to the direction of motion is generated between the rotating copper flywheel and the stationary magnetic components, macroscopically manifested as an eddy current damping force. Its mechanism involves converting external mechanical energy into eddy current heat energy, which is ultimately dissipated to the outside, achieving vibration reduction. This damper combines the inertial amplification effect of an inertial container with the non-contact, wear-free energy loss advantages of eddy current damping, making it suitable for lightweight vibration control of building structures. It features good durability, rapid response, and controllable output.
[0014] Furthermore, the magnetic component includes a back iron and permanent magnets arranged in a circumferential array on the surface of the back iron, with adjacent permanent magnets having opposite polarities. The back iron is circumferentially mounted on the inner wall of the inner cylinder. The circumferential array arrangement and the opposite polarities of adjacent permanent magnets form an alternating N-S-N-S array distribution. The permanent magnets at corresponding positions on the magnetic components located on both sides of the inertial flywheel have opposite polarities, thereby forming a complete closed magnetic circuit. This magnetic circuit configuration can generate a high-intensity, high-gradient magnetic field in the air gap region where the inertial flywheel is located.
[0015] Furthermore, the number of permanent magnets on the back iron surface is even, and the permanent magnets are uniformly distributed on the back iron surface. The uniform distribution of permanent magnets can improve the stability of the damper itself.
[0016] Furthermore, the damping unit includes at least one inertial flywheel and at least two magnetic components. The inertial flywheel and the back iron are arranged intersectingly, and the permanent magnets on the surface of the back iron facing the inertial flywheel are arranged in a circular array. The permanent magnets on the back iron on both sides of the inertial flywheel are arranged opposite each other with opposite polarities. The number of inertial flywheels can be selected according to the actual vibration reduction requirements, and the number of magnetic components can be adjusted accordingly. When the vibration reduction requirements are relatively small, one inertial flywheel and two magnetic components respectively located on both sides of the inertial flywheel can be set. As the vibration reduction requirements increase, the number of inertial flywheels can be gradually increased, and the number of magnetic components can be increased simultaneously.
[0017] Furthermore, the inertial flywheel maintains a uniform air gap with the inner cylinder and the permanent magnet, with no physical contact between them.
[0018] Furthermore, the housing includes two cover plates located at both ends, and a superelastic alloy plate mounted on the outside of the two cover plates. This encapsulation structure is simple, and the superelastic alloy plate used has a stable elastic recovery capability under tensile and compressive loads, further ensuring the self-resetting function of the damper and maximizing energy dissipation.
[0019] Furthermore, the elastic reset element is in a compressed state, and it is a single reset spring or multiple reset springs; when it is a single reset spring, the single reset spring is coaxially sleeved outside the inner cylinder, and its two ends are respectively connected to the two ends of the housing; when it is multiple reset springs, the multiple reset springs are arranged in a circumferential array outside the inner cylinder, and the two ends of the multiple reset springs are respectively connected to the two ends of the housing.
[0020] Furthermore, the end of the ball screw away from the ball nut is rotatably connected to the inner end face of the housing via an angular contact ball bearing.
[0021] Furthermore, it also includes two lifting lugs, which are respectively installed on the two outer end faces of the housing.
[0022] This invention proposes a rope-type eddy current inertial capacitive damper, which has the following advantages compared with the prior art:
[0023] 1. When relative displacement occurs at both ends of the damper, the inertial capacitive system converts the axial linear motion into the rotational motion of the inertial flywheel through a transmission mechanism consisting of a ball screw and a ball nut. This conversion mechanism makes the kinetic energy stored in the inertial flywheel and the angular deformation (rotational displacement of the inertial flywheel) significantly greater than the axial deformation at both ends of the damper. Under the same physical mass, it can generate an inertial force much greater than that of a traditional viscous damper, thus achieving a significant enhancement of the damping effect. At the same time, the rotational motion of the inertial flywheel provides the necessary relative motion conditions for the eddy current damping system.
[0024] 2. The magnetic components on both sides of the inertial flywheel together form a complete closed magnetic circuit. This magnetic circuit configuration can form a high-intensity, high-gradient magnetic field in the air gap region where the inertial flywheel is located. When it rotates and cuts the magnetic field, dense eddy currents are generated inside the flywheel, thereby efficiently generating a damping force opposite to the direction of motion, converting external mechanical energy into eddy current heat energy, and achieving the control effect of energy dissipation and structural vibration reduction.
[0025] 3. The inertial capacitive system and the eddy current damping system work together in terms of mechanical performance; the inertial capacitive system provides inertial force related to acceleration through mechanical transmission mechanism, thereby amplifying the apparent mass; the eddy current damping system provides damping force related to velocity through non-contact electromagnetic induction mechanism, thereby continuously dissipating mechanical energy; the synergistic effect of the two systems enables the damper to maintain a lightweight structure while possessing high-efficiency energy dissipation capability over a wide frequency band.
[0026] 4. When the damper undergoes axial relative displacement under external load, the reset system drives the damper back to its initial equilibrium position through its elastic restoring force, ensuring that the device has self-resetting function and continuous working capability, thereby achieving continuous dissipation of vibration energy under repeated loads and improving the post-earthquake recovery performance of the structure.
[0027] 5. The encapsulation system provides a stable, sealed working environment for the internal moving components of the damper, effectively isolating them from interference from external environmental factors such as dust and moisture. At the same time, the super-elastic alloy plate has a stable elastic recovery capability when subjected to tensile and compressive loads, ensuring that external excitation is effectively transmitted to the inside of the damper.

[0037] like Figure 1 , Figure 2 As shown, this embodiment provides a rope-type eddy current inertial capacitive damper, comprising:
[0038] The shell is a cavity structure;
[0039] An eddy current inertial capacitance unit is disposed inside the housing, including an inner cylinder 4, a ball screw 1, and a damping unit;
[0040] The bottom of the inner cylinder 4 is fixedly connected to one inner end face of the shell;
[0041] One end of the ball screw 1 is connected to a ball nut 3 fixed to the bottom of the inner cylinder 4, and a safety clearance is maintained between this end and the bottom of the inner cylinder 4, specifically as follows: Figure 3As shown; the other end of the ball screw 1 is rotatably connected to the other inner end face of the housing via a bearing;
[0042] The damping unit is disposed between the inner cylinder 4 and the ball screw 1, and includes an inertial flywheel 2 and a magnetic component arranged in an alternating manner. The inertial flywheel 2 is mounted on the ball screw 1, and the magnetic component is mounted on the inner wall of the inner cylinder 4.
[0043] An elastic reset member 5 is disposed inside the housing, and its two ends are respectively connected to the two ends of the housing.
[0044] Specifically, such as Figure 4 As shown, the magnetic component includes a back iron 8 and permanent magnets 7 arranged in a circular array on the surface of the back iron, with adjacent permanent magnets 7 having opposite polarities. The back iron 8 is circumferentially mounted on the inner wall of the inner cylinder 4. The number of permanent magnets 7 on the surface of the back iron 8 is even, and the permanent magnets 7 are uniformly distributed on the surface of the back iron. The circular array arrangement and the opposite polarities of adjacent permanent magnets 7 form an alternating N-S-N-S array distribution. The permanent magnets 7 at corresponding positions on the magnetic components on both sides of the inertial flywheel 2 have opposite polarities, thus forming a complete closed magnetic circuit. This magnetic circuit configuration can generate a high-intensity, high-gradient magnetic field in the air gap region where the inertial flywheel 2 is located. The uniform distribution of permanent magnets 7 can improve the stability of the damper itself.
[0045] The damping unit includes at least one inertial flywheel 2 and at least two magnetic components. The inertial flywheel 2 and the back iron 8 are arranged intersectingly, and the permanent magnets 7 are arranged in a circular array on the surface of the back iron 8 facing the inertial flywheel 2. The permanent magnets 7 on the back iron 8 on both sides of the inertial flywheel 2 are arranged opposite each other with opposite polarities, and the permanent magnets 7 at opposite positions on the same back iron 8 have the same polarity direction. A uniform air gap is maintained between the inertial flywheel 2, the inner cylinder 4, and the permanent magnets 7, with no physical contact. The number of inertial flywheels 2 can be selected according to the actual vibration reduction requirements, and the number of magnetic components can be adjusted accordingly. When the vibration reduction requirements are relatively small, one inertial flywheel 2 and two magnetic components respectively set on both sides of the inertial flywheel 2 can be set. As the vibration reduction requirements increase, the number of inertial flywheels 2 can be gradually increased, and the number of magnetic components can be increased simultaneously. Figure 1 The example shown includes two inertial flywheels 2.
[0046] During implementation, to ensure the reset function of the elastic reset element 5, it is necessary to ensure that the elastic reset element 5 is in a compressed state. Specifically, the elastic reset element 5 can be implemented using a single reset spring or multiple reset springs; when using a single reset spring, the single reset spring is coaxially sleeved outside the inner cylinder 4, and its two ends are respectively connected to the two ends of the shell. Figure 1 The image shows an example using a single return spring. When multiple return springs are used, they are evenly arranged in a circular array outside the inner cylinder 4, and both ends of each return spring are connected to both ends of the housing.
[0047] The housing includes two cover plates 6 located at both ends, and a superelastic alloy plate 9 installed on the outside of the two cover plates 6. This encapsulation structure is simple, and the superelastic alloy plate 9 has a stable elastic recovery capability under tensile and compressive loads, further ensuring the self-resetting function of the damper and maximizing energy dissipation.
[0048] In some embodiments, two lugs 10 are also included, which are respectively installed on the two outer end faces of the housing, so as to facilitate the connection of ropes to install the damper in a preset scene.
[0049] In the above embodiment, a rope-type eddy current inertial capacitive damper is provided:
[0050] (1) The inner cylinder 4, the ball screw 1, the ball nut 3 and the inertial flywheel 2 mounted on the ball screw 1 constitute an inertial-capacitive system. When the two ends of the damper are relatively displaced, the inertial-capacitive system converts the axial linear motion into the rotational motion of the inertial flywheel 2 through the transmission mechanism composed of the ball screw 1 and the ball nut 3. This conversion mechanism makes the kinetic energy stored in the inertial flywheel 2 and the angular deformation (rotational displacement of the inertial flywheel) significantly greater than the axial deformation at both ends of the damper. Under the same physical mass, it can generate an inertial force much greater than that of the traditional viscous damper, thus achieving a significant enhancement of the damping effect. At the same time, the rotational motion of the inertial flywheel 2 provides the necessary relative motion conditions for the eddy current damping system.
[0051] (2) The inertial flywheel 2 and the magnetic components constitute an eddy current damping system; the permanent magnets 7 are fixed on the back irons 8 on both sides in an even number, and the polarities of the adjacent permanent magnets 7 on the same side are alternately arranged to form an N-S-N-S array distribution. The permanent magnets 7 at corresponding positions on both sides of the inertial flywheel 2 have opposite polarities and together form a complete closed magnetic circuit. This magnetic circuit configuration can form a high-intensity, high-gradient magnetic field in the air gap region where the inertial flywheel 2 is located. When it rotates and cuts the magnetic field, dense eddy currents are generated inside the inertial flywheel 2, thereby efficiently generating a damping force opposite to the direction of motion, converting external mechanical energy into eddy current heat energy, and achieving the control effect of energy dissipation and structural vibration reduction.
[0052] (3) The inertial capacitive system and the eddy current damping system work together in terms of mechanical performance; the inertial capacitive system provides inertial force related to acceleration through mechanical transmission mechanism, thereby amplifying the apparent mass; the eddy current damping system provides damping force related to velocity through non-contact electromagnetic induction mechanism, thereby continuously dissipating mechanical energy; the two systems work together to enable the damper to maintain a lightweight structure while having high energy dissipation capability over a wide frequency band.
[0053] (4) The elastic reset component 5 constitutes the reset system; when the damper is subjected to external load and undergoes axial relative displacement, the reset system drives the damper back to the initial equilibrium position through its elastic restoring force, ensuring that the device has self-reset function and continuous working capability, thereby realizing continuous dissipation of vibration energy under repeated load and improving the post-earthquake recovery performance of the structure.
[0054] (5) The housing constitutes an encapsulation system; the encapsulation system provides a stable and sealed working environment for the internal moving components of the damper, effectively isolating the interference of external environmental factors such as dust and moisture. At the same time, the super-elastic alloy plate 9 has a stable elastic recovery capability when subjected to tensile and compressive loads, ensuring that external excitation is effectively transmitted to the inside of the damper.
[0055] The assembly process of this rope-type eddy current inertial capacitive damper follows the principle of inside-out and layered integration. Figure 1 The following is an example of a structure including two inertial flywheels, with the specific steps as follows: First, take the first annular back iron 8, and on its upper surface (for ease of explanation, let's take...) Figure 1(Illustrative diagram: left side is top, right side is bottom) An even number of permanent magnets 7 are arranged and fixed in a circular array with alternating polarities of N-S-N-S. Then, they are fitted onto the ball screw 1 and fixed to the corresponding positions on the inner wall of the inner cylinder 4. The first inertia flywheel 2 is fitted onto the preset shaft section of the ball screw 1, and then placed into the inner cylinder 4 from above, ensuring a uniform air gap between the inertia flywheel 2, the permanent magnets 7, and the inner wall of the inner cylinder 4, with no physical contact. A second back iron 8 is taken, and permanent magnets 7 are arranged on its lower surface with polarities of S-N-S-N. Another set of permanent magnets 7 is arranged on its upper surface with polarities of N-S-N-S, and then fitted onto the ball screw 1 and fixed to the corresponding positions on the inner wall of the inner cylinder 4. The second inertia flywheel 2 is fitted onto the ball screw 1, maintaining the air gap during insertion. Finally, a third back iron 8 is taken, and its lower surface is arranged with polarities of S-N-S-N. A permanent magnet 7 is arranged and fixed at the top of the inner cylinder 4; a ball nut 3 is fixed to the bottom of the inner cylinder 4, ensuring that the internal thread of the ball nut 3 engages with the thread of the ball screw 1. At the same time, sufficient safety clearance must be maintained between the end of the ball screw 1 and the bottom of the inner cylinder 4 to ensure that the ball nut 3 moves smoothly throughout the entire effective stroke of the ball screw 1; the internally integrated inner cylinder 4 assembly is fixed to a cover plate 6; the upper end of the ball screw 1 is connected to another cover plate 6 through an angular contact ball bearing. This bearing configuration can ensure that the ball screw 1 can withstand axial loads and achieve free rotation with low friction and high precision; an elastic reset member 5 is coaxially sleeved on the outside of the inner cylinder 4, and its two ends are fixed to the two cover plates 6 respectively; a super-elastic alloy plate 9 is installed on the outer end face of the two cover plates 6, completing all fastening steps, and sealing any possible moving interfaces.
[0056] Working principle: During implementation, the damper is installed in a preset scenario using lifting lugs and ropes. When the two cover plates 6 undergo relative displacement due to external load, the ball nut 3 drives the ball screw 1 to rotate, which in turn drives the inertial flywheel 2 to rotate at high speed. Based on the inertial capacitance effect, an amplified inertial force is generated, resulting in an inertial force on the inertial flywheel that is much greater than its physical mass. At the same time, the rotating copper inertial flywheel 2 moves relative to the permanent magnet 7 fixed on the inner cylinder 4. The inertial flywheel 2 moves by cutting magnetic field lines, generating eddy currents inside it. These eddy currents are subjected to Lorentz force in the magnetic field generated by the permanent magnet 7. The macroscopic effect is to generate a damping torque opposite to the rotation direction of the inertial flywheel 2. The mechanism is to convert external mechanical energy into eddy current heat energy, which is ultimately dissipated to the outside, achieving the purpose of vibration reduction. This collaborative working process simultaneously converts the externally input mechanical vibration energy into the rotational kinetic energy and eddy current thermal energy of the inertial flywheel 2, and finally achieves efficient vibration reduction through heat dissipation. It combines the advantages of inertial mass amplification and non-contact damping energy dissipation, and is suitable for lightweight vibration control of building structures. It features good durability, rapid response and controllable output.
[0057] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
