Description

Technical Field

[0001] This application relates to the technical field of vibration reduction and noise reduction of power equipment brackets, and particularly relates to a vibration reduction bracket. Background Art

[0002] The vibration and noise caused by power equipment will not only affect the normal operation of mechanical equipment, but also damage the structure seriously in severe cases. At the same time, the accompanying noise will also affect the environmental comfort of nearby personnel. How to reduce the vibration and noise generated by power equipment has become a key problem to be solved.

[0003] As a bracket for carrying power equipment, most of the vibration and noise of the power equipment are transmitted. The structure of the traditional power equipment base mainly considers factors such as the load-bearing capacity, stability, and spatial layout of the equipment during design. The common structure consists of the cross beam and support beam of the bracket, and rarely considers its vibration and noise conditions. Even if the vibration and noise conditions are considered, only rubber is added. When the power equipment is a rotating machine, the vibration reduction effect of rubber is poor. Summary of the Invention

[0004] This application provides a vibration reduction bracket, which can solve the problem of poor vibration reduction effect of the structure of the traditional power equipment base in the related art.

[0005] An embodiment of this application provides a vibration reduction bracket, including: an installation platform, on which there is a bearing area for carrying equipment; a bracket, which is connected to the installation platform; an acoustic black hole structure, which is arranged on the bracket; and an electromechanical resonance regulation unit, which is connected in the black hole area of the acoustic black hole structure, and the electromechanical resonance regulation unit is used to consume the vibration on the bracket.

[0006] By adopting the above technical solution: The acoustic black hole structure makes the wave speed of the bending wave approach zero when propagating to the black hole area through its geometric design with the thickness changing according to the power law, generating an energy concentration effect. This design concentrates the scattered vibration energy in the bracket to the black hole area. The electromechanical resonance regulation unit installed in the black hole area utilizes the energy concentration effect to achieve efficient energy conversion. When the vibration energy accumulates, the electromechanical resonance regulation unit converts mechanical energy into electrical energy, and a part of the electrical energy is dissipated as heat by the resistor.

[0007] In some embodiments, the bracket includes: a side frame, which is connected to one side of the installation platform; rib plates, which are located on both sides of the side frame. The rib plates have two mutually perpendicular installation surfaces, and one of the installation surfaces is fixed to the side frame, and the other installation surface is fixed to the installation platform; and the acoustic black hole structure is arranged on the rib plates.

[0008] By adopting the above technical solution: The side frame acts as the main load-bearing beam to bear axial vibration. The rib plate forms an L-shaped bending-resistant joint through double vertical installation surfaces, converting the lateral vibration of the installation platform into in-plane vibration of the rib plate, and making the vibration energy more efficiently conducted to the black hole area.

[0009] In some embodiments, the acoustic black hole structure is integrally formed by concave inward on the rib plate, and the formed cross-section of the acoustic black hole structure is arranged in an elliptical shape.

[0010] By adopting the above technical solution: The elliptical acoustic black hole structure can have a larger black hole area in the rib plate compared to the circular two-dimensional acoustic black hole, so as to have a lower cut-off frequency to achieve a better low-frequency vibration suppression effect.

[0011] In some embodiments, a plurality of cross beams are connected between the two rib plates, and each cross beam is arranged with a lower middle and higher ends, so that an acoustic black hole structure is also formed on the cross beam.

[0012] By adopting the above technical solution: The cross beam forces the vibration nodes of adjacent rib plates to be aligned, avoiding coupling with the passing frequency of common rotating machinery. The vibration energy is conducted through the rib plate to the cross beam and then to the black hole area path, increasing the dissipation distance compared to the direct propagation path, and having a better vibration damping effect.

[0013] In some embodiments, the middle part of the cross beam is set as the black hole area of the acoustic black hole structure, and the electromechanical resonance regulation unit is also provided in the black hole area on the cross beam.

[0014] By adopting the above technical solution: After the cross beam receives the vibration energy, the electromechanical resonance regulation unit converts mechanical energy into electrical energy, and a part of the electrical energy is dissipated as heat by the resistor. The electromechanical resonance regulation unit can adapt to the vibration characteristics of different devices.

[0015] In some embodiments, the electromechanical resonance regulation unit includes: a piezoelectric sheet, which is attached in the black hole area; an inductor; a resistor; and the positive and negative terminals of the piezoelectric sheet are connected in series with the inductor and the resistor through wires.

[0016] By adopting the above technical solution: The piezoelectric sheet converts the mechanical energy of the structural vibration into electrical energy, and a part of the electrical energy is dissipated as heat by the resistor. In addition, the inductor in the shunt circuit and the inherent capacitance of the piezoelectric sheet will alternately charge to generate electromagnetic resonance. At this time, a current in the opposite direction will be generated in the shunt circuit to react on the piezoelectric sheet, so as to make the piezoelectric sheet generate an opposite force, thus achieving an effect similar to that of a dynamic vibration absorber.

[0017] In some embodiments, rubber damping layers are provided on both the bracket and the cross beam within the acoustic black hole area.

[0018] By adopting the above technical solution: the rubber damping layer converts the vibration energy concentrated at the center of the acoustic black hole into heat energy, consumes most of the flexural wave energy, and produces a damping and vibration reduction effect.

[0019] In some embodiments, the rib plate is triangularly arranged, and a connecting rod is provided on one side of the hypotenuse of the rib plate. The two ends of the connecting rod are respectively fixed to the mounting platform and the side frame.

[0020] By adopting the above technical solution: the two ends of the connecting rod are respectively fixed to the mounting platform and the side frame. The hypotenuse of the rib plate serves as a waveguide channel to concentrate and direct the vibration energy to the connecting node of the connecting rod, creating conditions for subsequent dissipation by the acoustic black hole. Under the connection of the connecting rod, the load-bearing strength of the rib plate is also higher, providing a more stable support for the bracket.

[0021] In some embodiments, lifting lugs are provided on both the connecting rod and the side frame.

[0022] By adopting the above technical solution: lifting lugs are provided on both the connecting rod and the side frame, and thus the installation convenience can be improved by means of hoisting.

[0023] In some embodiments, mounting holes are provided on the mounting platform.

[0024] By adopting the above technical solution: the power equipment can be directly fixed through the mounting holes, and the connection is reliable.

[0025] The beneficial effects brought by the technical solution provided by the embodiments of the present application include:

[0026] The embodiments of the present application provide a vibration reduction bracket. The mounting platform serves as a basic support structure to provide a stable bearing surface for fixing the target equipment. The bracket connects the mounting platform and the acoustic black hole structure to transmit the vibration energy of the equipment. The acoustic black hole structure changes its structural thickness to achieve a change in structural impedance, so that the flexural wave velocity in the structure decreases, the wavelength becomes shorter, and the amplitude gradually increases. When the local thickness of the structure decreases to zero, the flexural wave velocity will also correspondingly decrease to zero. At the same time, all the vibration energy in the structure will also be concentrated at this position. Then, by setting an electromechanical resonance control unit in the black hole area, the mechanical vibration converged by the acoustic black hole is converted into electrical energy for dissipation, thereby reducing the vibration noise of the structure. The mounting platform and the bracket are responsible for static bearing, and the acoustic black hole and the electromechanical resonance control unit are responsible for dynamic vibration reduction. The two cooperate in design to achieve the wide-band vibration reduction and noise reduction effect of rotating mechanical equipment. Description of the Drawings

Specific implementation manners

[0034] To enable those skilled in the art to better understand the solution of the present application, the following clearly and completely describes the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present application.

[0035] The embodiment of the present application provides a shock-absorbing bracket, which can solve the problem of poor structural shock absorption of traditional power equipment bases in related technologies.

[0036] See Figures 1 to 5As shown in the figure, an embodiment of the present application provides a vibration damping bracket, including: a mounting platform 1, a bracket 2, an acoustic black hole structure 3, and an electromechanical resonance control unit 4. A bearing area for carrying equipment is provided on the mounting platform 1; the bracket 2 is connected to the mounting platform 1; the acoustic black hole structure 3 is arranged on the bracket 2; the electromechanical resonance control unit 4 is connected within the black hole region 6 of the acoustic black hole structure 3, and the electromechanical resonance control unit 4 is used to consume the vibration on the bracket 2.

[0037] When a power equipment, especially a rotating machine, is installed on the mounting platform 1, the acoustic black hole structure 3 makes the wave speed of the bending wave approach zero when propagating to the black hole region 6 through its geometric design with a power-law varying thickness, generating an energy concentration effect. This design concentrates the scattered vibration energy in the bracket 2 into the black hole region 6. The electromechanical resonance control unit 4 installed in the black hole region 6 utilizes the energy concentration effect to achieve efficient energy conversion. When the vibration energy accumulates, the electromechanical resonance control unit 4 converts mechanical energy into electrical energy, and a part of the electrical energy is dissipated as heat by the resistor 72. The electromechanical resonance control unit 4 can adapt to the vibration characteristics of different equipment. Therefore, the composite design between the acoustic black hole structure 3 and the electromechanical resonance control unit 4 comprehensively utilizes the control characteristics of both for vibration waves in different frequency bands, effectively achieving a broadband vibration damping and noise reduction effect of "one plus one greater than two".

[0038] In the present application, the provided bracket 2 includes: a side frame 20 and rib plates 21. The side frame 20 is connected to one side of the mounting platform 1, and the rib plates 21 are located on both sides of the side frame 20. The rib plates 21 have two mutually perpendicular mounting surfaces, and one of the mounting surfaces is fixed to the side frame 20, and the other mounting surface is fixed to the mounting platform 1. The side frame 20 serves as the main load-bearing beam to bear axial vibration. The rib plates 21 form an L-shaped bending-resistant node through the double perpendicular mounting surfaces, converting the lateral vibration of the mounting platform 1 into the in-plane vibration of the rib plates 21. Finally, the acoustic black hole structure 3 is arranged on the rib plates 21. Specifically, the acoustic black hole structure 3 is integrally formed inwards on the rib plates 21. The integral molding of the rib plates 21 and the acoustic black hole can eliminate the energy reflection at the bolt connection interface, making the vibration energy more efficiently conducted to the black hole region 6. And the formed cross-section of the acoustic black hole structure 3 is arranged in an elliptical shape. The thickness variation expression of the elliptical-designed acoustic black hole structure 3 is: where ∈ = h uni -h0 is the thickness decreasing coefficient; m is the power exponent, usually greater than 2, h0 is the minimum cut-off thickness, and is the uniform part thickness. The reason for choosing the elliptical acoustic black hole instead of the conventional circular two-dimensional acoustic black hole is that the acoustic black hole structure 3 can effectively suppress vibration above the cut-off frequency, but has a poor effect below the cut-off frequency. The relationship between the cut-off frequency of the two-dimensional acoustic black hole structure 3 and the area of the acoustic black hole region 6 can be described by the following formula: Therefore, the use of an elliptical acoustic black hole can have a larger black hole area 6 within the rib plate 21 compared to a circular two-dimensional acoustic black hole, thereby having a lower cut-off frequency to achieve a better low-frequency vibration suppression effect.

[0039] In this application, the rib plate 21 is arranged in a triangular shape, and a connecting rod 22 is provided on one side of the hypotenuse of the rib plate 21. The two ends of the connecting rod 22 are respectively fixed to the mounting platform 1 and the side frame 20. The hypotenuse serves as a waveguide channel to concentrate the vibration energy towards the connection node of the connecting rod 22, creating conditions for subsequent dissipation by the acoustic black hole. Under the connection of the connecting rod 22, the rib plate 21 also has a higher bearing strength, providing a more stable support for the bracket 2.

[0040] In this application, a plurality of cross beams 5 are also connected between the two rib plates 21. Each cross beam 5 is set with a lower middle and higher ends, so that an acoustic black hole structure 3 with a gradient stiffness distribution is also formed on the cross beam 5. The cross beam 5 forces the vibration nodes of the adjacent rib plates 21 to align, avoiding coupling with the passing frequency of common rotating machinery. The vibration energy is conducted through the rib plate 21 to the cross beam 5 and then to the black hole area 6 path, increasing the dissipation distance compared to the direct propagation path, and having a better vibration damping effect. Specifically, the thickness change formula of the acoustic black hole structure 3 on the cross beam 5 is: Where L is the length of the acoustic black hole, m is the power exponent, h0 is the minimum cut-off thickness, and ∈ is the thickness decreasing coefficient. To ensure that the one-dimensional acoustic has a lower cut-off frequency, when the mechanical strength is sufficient, the length of the acoustic black hole should be selected as large as possible.

[0041] In this application, the middle part of the cross beam 5 is set as the black hole area 6 of the acoustic black hole structure 3, and an electromechanical resonance control unit 4 is also provided in the black hole area 6 on the cross beam 5. After the cross beam 5 receives the vibration energy, the electromechanical resonance control unit 4 converts mechanical energy into electrical energy, and a part of the electrical energy is dissipated as heat by the resistor 72. The electromechanical resonance control unit 4 can adapt to the vibration characteristics of different devices.

[0042] In this application, the electromechanical resonance control unit 4 includes: a piezoelectric sheet 70 made of PZT-5H material, an inductor 71, and a resistor 72. The piezoelectric sheet 70 is attached in the black hole area 6, and the positive and negative terminal ends of the piezoelectric sheet 70 are connected in series with the inductor 71 and the resistor 72 through wires. Its working principle is that the piezoelectric sheet 70 converts the mechanical energy of the structural vibration into electrical energy, and a part of the electrical energy is dissipated as heat by the resistor 72. In addition, the inductor 71 in the shunt circuit and the inherent capacitance of the piezoelectric sheet 70 will alternately charge to generate electromagnetic resonance. At this time, a current in the opposite direction will be generated in the shunt circuit and act on the piezoelectric sheet 70 in the opposite direction, so that the piezoelectric sheet 70 generates an opposite force, thus achieving an effect similar to that of a dynamic vibration absorber. The L-C resonance frequency expression of the circuit is: Among them, f0 is the circuit resonance frequency, and L is the adjustable mode in the external circuit. When the piezoelectric sheet 70 has the maximum energy conversion ability. Therefore, when the power equipment is a rotating machine, its main low-order vibration frequencies are the shaft frequency and the blade frequency, and their expressions are: Among them, f shaft is the shaft frequency, f blade is the blade frequency, k is the number of blades, and N is the rotational speed. So at this time, the value of the analog inductor 71 can be adjusted according to the rotational speed of the rotating machine under different working conditions to tune the resonance frequency of the external circuit to be consistent with the vibration frequency of the rotating machine, thereby realizing dynamic and targeted control of the low-frequency vibration of the rotating machine power equipment. The equivalent inductance value of the inductor 71 is where R1, R2, R3, and R4 are the resistances 72 of the circuit, and C is the capacitance in the circuit.

[0043] In this application, to further improve the anti-vibration effect of the bracket 2, rubber damping layers 8 are also provided on both the bracket 2 and the cross beam 5 within the acoustic black hole region 6. The damping material layer is made of rubber or a polymer. The rubber damping layer 8 converts the vibration energy concentrated at the center of the acoustic black hole into heat energy, consumes most of the bending wave energy, and produces a damping and vibration reduction effect. Compared with the design of rubber on the traditional bracket 2, based on the technology of the acoustic black hole structure 3 in this application, the rubber damping layer 8 here can be made smaller, making the bracket 2 lighter.

[0044] In this application, the designed bracket 2 serves as the installation foundation of the power equipment and is generally fixed on the wall for use. To facilitate the installation of the bracket 2, lifting lugs 9 are provided on both the connecting rod 22 and the side frame 20, and thus the installation convenience can be improved through the lifting method. Additionally, installation holes 10 are provided on the installation platform 1, and the power equipment can be directly fixed through the installation holes 10, with reliable connection.

[0045] The implementation principle of the embodiments of this application is as follows: A vibration damping support includes: a mounting platform 1, a bracket 2, an acoustic black hole structure 3, and an electromechanical resonance control unit 4. When a power device, especially a rotating machine, is installed on the mounting platform 1, the acoustic black hole structure 3, through its geometric design with a power-law variation in thickness, causes the bending wave speed to approach zero when propagating to the black hole region 6, generating an energy concentration effect. This design concentrates the scattered vibration energy in the bracket 2 to the black hole region 6. The electromechanical resonance control unit 4 can adapt to the vibration characteristics of different devices. The electromechanical resonance control unit 4 installed in the black hole region 6 utilizes the energy concentration effect to achieve efficient energy conversion. When the vibration energy accumulates, the electromechanical resonance control unit 4 converts mechanical energy into electrical energy, and a part of the electrical energy is dissipated as heat by the resistor 72. Another reason for choosing an elliptical acoustic black hole instead of a conventional circular two-dimensional acoustic black hole on the rib plate 21 is that the acoustic black hole structure 3 can effectively suppress vibration above the cut-off frequency, but has a poor effect below the cut-off frequency. The elliptical acoustic black hole can have a larger area of the black hole region 6 compared to the circular two-dimensional acoustic black hole in a triangular region such as the triangular rib plate 21, thus having a lower cut-off frequency to achieve a better low-frequency vibration suppression effect. Further, a plurality of cross beams 5 are connected between the two rib plates 21, and each cross beam 5 is set with a lower middle and higher ends, so that an acoustic black hole structure 3 with a gradient stiffness distribution is also formed on the cross beam 5. The cross beam 5 forces the vibration nodes of the adjacent rib plates 21 to be aligned, avoiding coupling with the passing frequency of common rotating machinery. The vibration energy is conducted through the rib plate 21 to the cross beam 5 and then to the black hole region 6, increasing the dissipation distance compared to the direct propagation path, and having a better vibration damping effect. The designed electromechanical resonance control unit 4 specifically includes a piezoelectric sheet 70 made of PZT-5H material, an inductor 71, and a resistor 72. The piezoelectric sheet 70 is attached inside the black hole region 6, and the positive and negative terminal ends of the piezoelectric sheet 70 are connected in series with the inductor 71 and the resistor 72 through wires. Its working principle is that the piezoelectric sheet 70 converts the mechanical energy of the structural vibration into electrical energy, and a part of the electrical energy is dissipated as heat by the resistor 72. In addition, the inductor 71 in the shunt circuit and the inherent capacitance of the piezoelectric sheet 70 will alternately charge to generate electromagnetic resonance. At this time, a current in the opposite direction will be generated in the shunt circuit and act on the piezoelectric sheet 70 in the opposite direction, so that the piezoelectric sheet 70 generates an opposite force, thus achieving an effect similar to a dynamic vibration absorber. The electromechanical resonance control unit 4 can adjust the value of the simulated inductor 71 according to the rotational speed of the rotating machine under different working conditions to tune the resonance frequency of the external circuit to be consistent with the vibration frequency of the rotating machine, thereby realizing dynamic and targeted control of the low-frequency vibration of the rotating machine power device.
