Description

Technical Field

[0001] This invention relates to the field of nonlinear vibration suppression, and in particular to a load-bearing enhanced multidimensional bionic vibration isolator and its working method. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Significant progress has been made in the theory and application of nonlinear vibration isolation over the past decade. Increasing attention is being paid to the ability of nonlinear stiffness-damped isolators to effectively reduce the response near the resonant frequency while maintaining superior high-frequency vibration isolation performance. However, existing quasi-zero stiffness isolators are mostly based on a three-spring structure, with three spring structures arranged on the left, right, and bottom sides of the isolated platform, where the left and right spring structures provide negative stiffness. This structure utilizes a combination of spring structures with multiple dimensions to suppress single-dimensional vertical vibrations, making it difficult to suppress multi-dimensional vibrations.

[0004] However, the use of smart materials such as shape memory alloys and piezoelectric crystals to achieve multidimensional low-frequency vibration isolation has limited load-bearing capacity, making it difficult to achieve multidimensional low-frequency vibration isolation for large mass components such as spindles.

[0005] In other words, existing vibration isolation mechanisms suffer from the problem of not being able to unify load-bearing capacity with multi-dimensional low-frequency vibration isolation. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a load-bearing enhanced multidimensional bionic vibration isolator that can decouple vibrations in multiple dimensions and effectively isolate low-frequency vibrations in each dimension.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0008] A load-bearing enhanced multidimensional bionic vibration isolator includes a vibration damping component, an inner ring component, and an outer ring component arranged sequentially from the inside to the outside. The inner ring component and the outer ring component are connected by a vibration damping support. Multiple rhomboid bionic limb-shaped vibration damping mechanisms are connected between the vibration damping component and the inner ring component. The multiple rhomboid bionic limb-shaped vibration damping mechanisms are located on the same plane but in different directions. The vibration damping component includes an anti-torsion support that supports the vibration damping platform. A first damping component is connected to the side of the anti-torsion support to provide damping in the Z-direction. Adjacent rhomboid bionic limb-shaped vibration damping mechanisms are spaced at an angle and connected by an elastic element. The rhomboid bionic limb-shaped vibration damping mechanism is connected to the anti-torsion support. An elastic component is provided inside the rhomboid bionic limb-shaped vibration damping mechanism.

[0009] As described above, in a load-bearing enhanced multidimensional bionic vibration isolator, the rhomboid bionic limb-shaped vibration damping mechanism is provided in at least two forms around the anti-torsion support;

[0010] The cross-sectional shape of the outer ring component is the same as that of the inner ring component. The position of the rhomboid bionic limb-shaped vibration damping mechanism corresponds one-to-one with the position of the vibration damping support. The rhomboid bionic limb-shaped vibration damping mechanism is provided on each side of the inner ring component so that each side of the inner ring component is provided with a rhomboid bionic limb-shaped vibration damping mechanism to ensure the vibration damping effect.

[0011] In another embodiment of the load-bearing enhanced multidimensional bionic vibration isolator described above, a middle ring component is provided between the inner ring component and the outer ring component, and the vibration damping support is provided between the middle ring component and the outer ring component. A rhomboid bionic limb-shaped vibration damping mechanism is connected between the middle ring component and the inner ring component, thus forming a multi-ring structure. This creates a multi-layer vibration isolation structure within a limited space, further improving the vibration isolation performance and accumulating and expanding the anti-vibration displacement, which ultimately converges at the central vibration isolation component, while also taking into account the anti-torsional effect.

[0012] As described above, in a load-bearing enhanced multidimensional bionic vibration isolator, a second damping component is further connected between the inner ring component and the middle ring component. The second damping component is located on both sides of the rhomboid bionic limb-shaped vibration reduction mechanism between the middle ring component and the inner ring component, thereby further ensuring the vibration reduction and isolation effect.

[0013] As described above, a load-bearing enhanced multidimensional bionic vibration isolator includes a rhomboid bionic limb-shaped vibration damping mechanism comprising opposing support seats, one side of each of the support seats being movably connected to two connecting members, and the other side of each connecting member being movably connected to a connecting member connected to another support seat. One support seat is connected to the anti-torsion support, and the other support seat is connected to the inner ring member. The elastic component connects the connecting members on both sides, thus forming a closed-loop rhomboid mechanism.

[0014] As described above, in a load-bearing enhanced multidimensional bionic vibration isolator, the connecting member is a linear angle bracket with multiple openings, and the connecting member is connected to the support base through a damping hinge joint to provide frictional damping.

[0015] As described above, a load-bearing enhanced multidimensional bionic vibration isolator includes an elastic component comprising a first tension spring connected to the connection points of the connecting members on both sides, a second tension spring and a third tension spring respectively located on both sides of the first tension spring, with the ends of the second tension spring and the third tension spring respectively connected to the corresponding connecting members. The elastic component is initially in a pre-stretched state to ensure the vibration damping effect of the rhomboid bionic limb-shaped vibration reduction mechanism.

[0016] As described above, in a load-bearing enhanced multidimensional bionic vibration isolator, the support base is a T-shaped support base with two through holes, and the support base is connected to the connecting member on the corresponding side through the two through holes;

[0017] The elastic element is a diagonal tension spring, and both ends of the elastic element are connected to the connection points of the connecting elements in the two adjacent rhomboid bionic limb-shaped vibration damping mechanisms.

[0018] As described above, in a load-bearing enhanced multidimensional bionic vibration isolator, the first damping component is a spring-damped vibration isolator, an air-damped vibration isolator, or a nonlinear vibration isolator, and the second damping component is a spring damper.

[0019] The anti-torsion support is a damping disc, with a spring damper and an anti-torsion disc spring connected to both sides of the damping disc. The spring damper is used to suppress vibration in the normal direction of the vibration damping platform. A first sleeve is sleeved on the outside of the anti-torsion disc spring, a second sleeve is sleeved on the outside of the first sleeve, and a third sleeve is sleeved on the outside of the second sleeve. The third sleeve is connected to the rhomboid bionic limb-shaped vibration damping mechanism. The first and third sleeves are flexible sleeves, and the second sleeve is a rigid sleeve. By combining multiple sleeves, vibration of three degrees of freedom can be suppressed, but the inertial buffering characteristics of torsional vibration in the normal direction of the vibration damping platform can be preserved.

[0020] Thirdly, the present invention also provides a method for operating a load-bearing enhanced multidimensional bionic vibration isolator, comprising the following:

[0021] External vibrations are isolated by the vibration damping supports between the inner and outer ring components, and the vibration-resistant displacement is accumulated and amplified. The external vibrations are transmitted to the rhomboid bionic limb-shaped vibration damping mechanism. The elastic components in the rhomboid bionic limb-shaped vibration damping mechanism provide damping, and the elastic components between the rhomboid bionic limb-shaped vibration damping mechanisms provide further damping. In this way, vibrations are effectively suppressed in multiple directions in the XYZ three-dimensional space. The vibrations are further transmitted to the vibration damping component. The anti-torsion component and the first damping component in the vibration damping component further effectively suppress the vibrations, realizing the decoupling of vibrations in the three dimensions and effectively isolating vibrations in each dimension.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1) The bionic vibration isolator provided by the present invention includes a vibration damping component, an inner ring component and an outer ring component arranged sequentially from the inside to the outside. Multiple rhomboid bionic limb-shaped vibration damping mechanisms are connected between the vibration damping component and the inner ring component. External vibration is transmitted to the vibration damping component through the rhomboid bionic limb-shaped vibration damping mechanisms. The external vibration is transmitted gradually towards the center. During the transmission process, damping is provided by the vibration damping support, the rhomboid bionic limb-shaped vibration damping mechanism, the elastic element and the anti-torsion support, and the first damping component to effectively suppress the vibration.

[0024] 2) In another embodiment of the present invention, a middle ring component is provided between the inner ring component and the outer ring component, a vibration damping support is provided between the middle ring component and the outer ring component, and a rhomboid bionic limb-shaped vibration damping mechanism is connected between the middle ring component and the inner ring component, thus forming a multi-ring structure, forming a multi-layer vibration isolation structure in a limited space, further improving the vibration isolation performance, and accumulating and expanding the anti-vibration displacement, which finally converges at the central vibration isolation component, while also taking into account the anti-torsion effect.

[0025] 3) The rhomboid bionic limb-shaped vibration damping mechanism in this invention has a reasonable structure. The support bases are arranged opposite each other, which facilitates the setting of the connecting parts. The connecting parts are connected to the support bases through a damping hinge joint to provide frictional damping. The elastic component connects the connecting parts on both sides. The elastic component is initially in a pre-stretched state to ensure the vibration damping effect of the rhomboid bionic limb-shaped vibration damping mechanism.

[0026] 4) In this invention, the anti-torsion support is a damping disk. The first damping component is connected to the damping disk by multiple sleeves. The first sleeve and the third sleeve are flexible sleeves, and the second sleeve is a rigid sleeve. The combination of multiple sleeves can suppress the vibration of the three degrees of freedom of movement, but can retain the inertial buffering characteristics of torsional vibration in the normal direction of the vibration suppression platform.

[0037] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0038] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0039] As introduced in the background section, although nonlinear stiffness damping vibration isolators can effectively reduce the response near the resonance frequency while maintaining good high-frequency vibration isolation performance, existing products have problems such as difficulty in suppressing multidimensional vibration and limited load-bearing capacity. This invention proposes a load-bearing enhanced multidimensional bionic vibration isolator.

[0040] Example 1

[0041] In a typical embodiment of the present invention, reference is made to Figure 2 and Figure 3As shown, a load-bearing enhanced multidimensional bionic vibration isolator includes a vibration damping component, an inner ring component 3, and an outer ring component 4 arranged sequentially from the inside to the outside. The inner ring component 3 and the outer ring component 4 are connected by a vibration damping support 5. Multiple rhomboid bionic limb-shaped vibration damping mechanisms 1 are connected between the vibration damping component and the inner ring component. The multiple rhomboid bionic limb-shaped vibration damping mechanisms 1 are located on the same plane but in different directions. The vibration damping component includes an anti-torsion support 7, which supports the vibration damping platform. A first damping component 8 is connected to the side of the anti-torsion support 7 to provide damping in the Z direction. Adjacent rhomboid bionic limb-shaped vibration damping mechanisms 1 are spaced at an angle and connected by an elastic element 2. The rhomboid bionic limb-shaped vibration damping mechanism 1 is connected to the anti-torsion support 7. An elastic component is provided inside the rhomboid bionic limb-shaped vibration damping mechanism.

[0042] In this embodiment, four rhomboid bionic limb-shaped vibration damping mechanisms 1 are provided around the anti-torsion support 7, and the angle between two adjacent rhomboid bionic limb-shaped vibration damping mechanisms 1 is 90°, so that four rhomboid bionic limb-shaped vibration damping mechanisms 1 are symmetrically arranged around the anti-torsion support.

[0043] Specifically, the outer ring component 4 is a square tube, and the inner ring component 3 is also a square tube. The cross-sectional shape of the outer ring component 4 is the same as that of the inner ring component. The position of the rhomboid bionic limb-shaped vibration damping mechanism 1 corresponds one-to-one with the position of the vibration damping support. The rhomboid bionic limb-shaped vibration damping mechanism 1 is provided on each side of the inner ring component 3 so that each side of the inner ring component 3 is provided with the rhomboid bionic limb-shaped vibration damping mechanism 1 to ensure the vibration damping effect.

[0044] refer to Figure 1 As shown, the rhomboid biomimetic limb-shaped vibration damping mechanism 1 includes two opposing support seats. Specifically, the support seats are double-hole T-shaped support seats, namely the first double-hole T-shaped support seat 1-1 and the second double-hole T-shaped support seat 1-8. That is, each support seat is provided with two through holes, and the two through holes are spaced apart. The double-hole T-shaped support seats are connected to the connectors through damping hinge joints such as hinge joint studs 1-3 to provide damping. The first double-hole T-shaped support seat 1-1 is connected to the anti-torsion support 7, and the second double-hole T-shaped support seat 1-8 is connected to the inner ring component.

[0045] Moreover, the rhomboid biomimetic limb-shaped vibration damping mechanism 1 has strong cubic stiffness and cubic nonlinear damping characteristics when the distance between the two double-hole T-shaped support seats is closer, which can reduce the force transmission rate at the resonant frequency and is not affected in other frequency domains.

[0046] The connecting component is a linear angle bracket, which has multiple holes. The first double-hole T-shaped support 1-1 is connected to the first linear angle bracket 1-2 and the second linear angle bracket 1-10 through two through holes on it. The second double-hole T-shaped support is connected to the third linear angle bracket 1-9 and the fourth linear angle bracket 1-7 through two through holes on it. The second linear angle bracket 1-10 and the third linear angle bracket 1-9 are hinged together, and the first linear angle bracket 1-2 and the fourth linear angle bracket 1-7 are hinged together, thus forming a closed-loop rhomboid mechanism.

[0047] It should be noted that the first double-hole T-shaped support 1-1 and the second double-hole T-shaped support 1-8 are made of polyurethane rubber material with certain vibration reduction and noise reduction functions.

[0048] It is easily understood that the elastic component includes a first tension spring 1-5, which connects to the joints of the two connecting parts. The first tension spring is located on the short diagonal of the rhomboid bionic limb-shaped vibration damping mechanism. A second tension spring 1-4 and a third tension spring 1-6 are respectively located on both sides of the first tension spring. The second and third tension springs 1-4 and 1-6 are parallel to the first tension spring 1-5, and the distance between the second and third tension springs 1-4 and 1-6 and the first tension spring 1-5 is less than the distance between the second and third tension springs 1-4 and 1-6 and the first tension spring 1-5. The distance between the corresponding side support seats, the two ends of the second tension spring 1-4 and the third tension spring 1-6 are respectively connected to the corresponding connecting parts. The elastic components are initially in a pre-tensioned state to ensure the vibration damping effect of the rhomboid bionic limb-shaped vibration damping mechanism. The free length and pre-tension amount of the above three tension springs are adjusted proportionally according to similar geometric relationships to reduce the stress concentration of the first tension spring 1-5 and the damping hinge joint connected to it, and provide load-bearing capacity. In this way, the rhomboid bionic limb-shaped vibration damping mechanism is equivalent to a vibration isolation mechanism with greater stiffness and damping.

[0049] It is easy to understand that the ends of each tension spring are connected to the corresponding linear angle brackets through damping hinge joints; multiple tension springs are linearly adjustable dampers, and the linear damping is transmitted through the rhomboid structure, introducing nonlinearity of structural damping. As the speed increases, the damping force will increase in a nonlinear way, thereby providing a greater damping effect near the resonance frequency and reducing the vibration response of the bionic vibration isolator.

[0050] In addition, the elastic element is a diagonal tension spring 2, and the two ends of the elastic element are respectively connected to the connection points of the straight angle brackets in the two adjacent rhomboid bionic limb-shaped vibration damping mechanisms.

[0051] refer to Figure 6As shown, the anti-torsion support 7 is a damping disk 7-1 with adjustable rotational damping. The damping disk 7-1 supports the vibration damping platform 6, which can be a rectangular platform. Spring dampers 9 and anti-torsion disc springs 7-2 are respectively connected to both sides of the damping disk 7-1. The spring dampers 9 suppress vibration in the normal direction of the vibration damping platform. The anti-torsion disc spring 7-2 is fitted with a first sleeve 7-3, which is fitted with a second sleeve 7-4. The second sleeve 7-4 is fitted with a third sleeve, which is connected to the rhomboid bionic limb-shaped vibration damping mechanism. The first sleeve 7-3 and the third sleeve are flexible sleeves, while the second sleeve 7-4 is a rigid sleeve. By combining multiple sleeves, the vibration of three degrees of freedom can be suppressed, but the inertial buffering characteristics of torsional vibration in the normal direction of the vibration damping platform can be preserved.

[0052] Specifically, the first sleeve 7-3 is a polyurethane round sleeve, the third sleeve is a square polyurethane rubber sleeve, the steel sleeve is tightly fitted with both the polyurethane round sleeve and the square polyurethane rubber connecting sleeve, and the third sleeve has multiple connecting holes evenly distributed around its perimeter. These multiple connecting holes are used to connect the first double-hole T-shaped support 1-1 of the rhomboid bionic limb-shaped vibration damping mechanism.

[0053] In this embodiment, the first damping component 8 is a spring-damped vibration isolator, an air-damped vibration isolator, or a nonlinear vibration isolator.

[0054] It should be noted that the key connecting components of the anti-torsion support and the rhomboid biomimetic limb-shaped vibration damping mechanism, such as the support base, are all made of flexible polyurethane material with vibration damping and sound insulation properties. When subjected to alternating stress, the polyurethane material can store some energy and exhibit elasticity, while dissipating some energy through intermolecular internal friction and exhibiting viscosity. Compared with the rigid connecting parts of the past, it has better damping and vibration reduction characteristics within a certain load-bearing capacity range.

[0055] In other examples, the anti-torsion support 7 can be replaced with a bearing to suppress vibration of shaft parts.

[0056] It is easy to understand that during the test, the outer ring component 4 is connected to the excitation platform (vibration mechanism) by bolts or is made as a single unit to simulate the lateral vibration excitation applied to the vibration isolation device from the outside. Triangular ribs are provided at the connection between the outer ring component 4 and the base of the excitation platform to suppress the vibration amplification caused by the vibration transmitted by the shell. Multiple closely arranged universal ball supports 11 are provided on the inner side of the outer ring component 4. Each universal ball support 11 is in contact with the vibration damping support 5. The vibration damping support 5 is a rubber vibration damping support with large lateral stiffness, which can prevent swaying and ensure that the horizontal two-dimensional vibration damping structure can move in the vertical direction, minimizing the mutual coupling of vibration in the two directions.

[0057] Example 2

[0058] The difference between this embodiment and Embodiment 1 is that:

[0059] Based on Example 1, and referring to Figure 4 and Figure 5 As shown, a middle ring component is set between the inner and outer ring components, and a vibration damping support is set between the middle and outer ring components. The middle ring component is also a rectangular tube. The distance between the middle ring component and the outer ring component is smaller than the distance between the middle ring component and the inner ring component. A rhomboid bionic limb-shaped vibration damping mechanism is connected between the middle ring component and the inner ring component. The rhomboid bionic limb-shaped vibration damping mechanism here and the extension line of the rhomboid bionic limb-shaped vibration damping mechanism set in the inner ring component form a multi-ring structure, forming a two-stage planar multi-dimensional vibration isolator. In a limited space, a multi-layer vibration isolation structure is formed, which further improves the vibration isolation performance and accumulates and expands the anti-vibration displacement, which finally converges at the central vibration isolation component, and also takes into account the anti-torsional effect.

[0060] In other examples, by adding a middle ring component, multi-level planar multi-dimensional vibration isolators can be constructed according to space and vibration isolation requirements.

[0061] Furthermore, a second damping component 9 is connected between the inner ring component and the middle ring component. The second damping component is a spring damper 9, which uses a compression spring. Initially, all spring dampers are in a pre-compressed state. The second damping component is located on both sides of the rhomboid bionic limb-shaped vibration damping mechanism between the middle ring component and the inner ring component. The second damping component further ensures the vibration reduction and isolation effect. When the spring dampers 9 in the rhomboid bionic limb-shaped vibration damping mechanism 1 are all pre-tensioned springs, the rhomboid bionic limb-shaped vibration damping mechanism 1 is a positive stiffness element. Spring dampers 9 perpendicular to the pre-tensioned spring direction can be connected in parallel on both sides to provide negative stiffness. The parallel combination of the negative stiffness mechanism and the positive stiffness mechanism can achieve a dynamic stiffness close to zero at certain specific operating points, obtain a small dynamic response, and improve the stability of each level of vibration isolator.

[0062] The biomimetic vibration isolator provided in this embodiment includes a vibration damping component, an inner ring component, and an outer ring component arranged sequentially from the inside to the outside. Multiple rhomboid biomimetic limb-shaped vibration damping mechanisms are connected between the vibration damping component and the inner ring component. External vibrations are transmitted to the vibration damping component through the rhomboid biomimetic limb-shaped vibration damping mechanisms, and the external vibrations are gradually transmitted towards the center. During the transmission process, the vibration is effectively suppressed by providing damping through the vibration damping support, the rhomboid biomimetic limb-shaped vibration damping mechanism, the elastic element and the anti-torsion support, and the first damping component. By utilizing the limited three-dimensional space, the traditional structure can only achieve effective low-frequency vibration isolation in one dimension. This improves the decoupling of vibrations in three dimensions and provides effective low-frequency vibration isolation for each dimension.

[0063] Example 3

[0064] This embodiment provides a working method for a load-bearing enhanced multidimensional bionic vibration isolator, including the following:

[0065] External vibrations are isolated by the vibration damping supports between the inner and outer ring components, and the vibration-resistant displacement is accumulated and amplified. The external vibrations are transmitted to the rhomboid bionic limb-shaped vibration damping mechanism. The elastic components in the rhomboid bionic limb-shaped vibration damping mechanism provide damping, and the elastic components between the rhomboid bionic limb-shaped vibration damping mechanisms provide further damping. In this way, vibrations are effectively suppressed in multiple directions in the XY plane. The vibrations are further transmitted to the vibration damping component. The anti-torsion component and the first damping component in the vibration damping component further effectively suppress the vibrations, realizing the decoupling of vibrations in the three dimensions and effectively isolating vibrations in each dimension.

[0066] In the second embodiment, the vibration is transmitted through the rhomboid bionic limb-shaped vibration damping mechanism between the inner ring component and the middle ring component, and then through the spring damper 9 to the rhomboid bionic limb-shaped vibration damping mechanism inside the inner ring component, and then gradually transmitted inward.

[0067] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

The working method of a load-bearing enhanced multidimensional bionic vibration isolator according to any one of claims 1-9, characterized in that, Includes the following: External vibrations are isolated by the vibration damping supports between the inner and outer ring components, and the vibration-resistant displacement is accumulated and amplified. The external vibrations are transmitted to the rhomboid bionic limb-shaped vibration damping mechanism. The elastic components in the rhomboid bionic limb-shaped vibration damping mechanism provide damping, and the elastic components between the rhomboid bionic limb-shaped vibration damping mechanisms provide further damping. In this way, vibrations are effectively suppressed in multiple directions in the XY plane. The vibrations are further transmitted to the vibration damping component. The anti-torsion component and the first damping component in the vibration damping component further effectively suppress the vibrations, realizing the decoupling of vibrations in the three dimensions and effectively isolating vibrations in each dimension.
