Description

Technical Field

[0001] This invention relates to the field of vibration reduction and isolation control technology, specifically to a vibration reduction and isolation device. Background Technology

[0002] Vibration damping and isolation bearings can be widely used in civil engineering, machinery and equipment, transportation, bridges, aviation, aerospace, energy engineering, power engineering, pipeline engineering, subway tunnels, seats, structures and facilities, and other areas that require vibration damping and isolation. They can achieve the functions of saving energy, reducing adverse emissions, protecting the natural environment, improving living conditions, accumulating social wealth, enriching society, improving the level of civilization, practicing the harmonious coexistence of mankind and nature, and jointly creating a green development environment.

[0003] To meet the different needs of seismic isolation and vibration reduction, different types of supports with relatively movable upper and lower supports have been developed. These supports have their own advantages, as well as disadvantages and problems.

[0004] 1. A double-sided limiting friction sliding support (ZL01115216.8, International Patent Main Classification No. E04B 1 / 98): The disadvantage and problem of the support is that under the action of an external force perpendicular to the translation, it cannot guarantee that the upper and lower sliding surfaces of the support device will not separate. Once they separate vertically, the supported body loses safety control.

[0005] 2. Straight-sliding friction sliding support (ZL01212976.3): The disadvantage and problem of this support is that under the action of external force, it cannot limit the amount of displacement in the friction sliding direction and the amount of displacement under the action of separation in the perpendicular direction of friction sliding.

[0006] 3. A vibration-controlled friction sliding support (ZL01106775.6, International Patent Classification No. E04B 1 / 98): The shortcomings and problems of this support are that it is original and has a strong principle, but in terms of practicality, it has problems with displacement limitation and insufficient conditions for solving rigid collision.

[0007] Due to some shortcomings and problems of the above-mentioned bearings, there are insufficient functions, defects and hidden dangers in use, which leads to complexity and tortuousness in design and calculation. There is a situation where the research on vibration reduction and isolation and vibration control theory tends to be advanced, but the practical application encounters bottlenecks, resulting in a problem that the theoretical requirements do not match the current status of bearing technology.

[0012] Furthermore, the rolling elements are placed inside a cage, which is a perforated support; the cage horizontally controls the rolling elements so that they maintain a distance from each other during rolling; the number of holes in the cage is the same as the number of rolling elements.

[0013] Furthermore, the lateral deformation component is a combination of any two of the following: a truncated conical helical spring assembly, a bushing-type radial spring, and a bushing-type radial wave spring.

[0014] Furthermore, the vertical spring assembly includes a bushing-type axial wave spring 8 and a spring assembly component 8-1; the bushing-type axial wave spring 8 and the spring assembly component 8-1 are respectively on both sides of the support axis of symmetry.

[0019] The beneficial effects of this invention are as follows:

[0020] (1) The support involved in this invention has the functions of vertical vibration reduction and isolation, horizontal vibration reduction and isolation, and resetting; the support can limit the horizontal displacement and reduce vertical vibration and vibration; it has multiple functions, is mutually harmonious, has a small area, is convenient and simple to use, and can play a beneficial role in the active control and passive control of vibration and vibration source.

[0021] (2) The present invention has a stress-strain-pressure sensing component in the direction of the bearing force of the support, which has the detection functions of vertical and horizontal vibration reduction and isolation, and vibration reduction and isolation. It can provide conditions for measuring the magnitude of the force on the support at any time, and can monitor the action of the objects connected to the support, and verify the design, calculation and construction quality in the early stage. It opens up a way for the scientific, digital and group control of the support field in the future.

[0022] (3) This invention obtains numerical action force for controlling vibration reduction and isolation through friction: Due to the different influence trends of pressure change on sliding friction coefficient and rolling friction coefficient, combined sliding friction and rolling friction have special advantages over sliding friction and rolling friction. The initial friction coefficient, displacement friction coefficient and termination friction coefficient of the support friction tend to be consistent, providing accurate action values ​​for vibration reduction and isolation. After the friction layer is sprayed on the friction pair, lubricating oil is added. The oil storage effect of the micropores in the coating can protect the coating and reduce and stabilize the friction coefficient. The groove reserved in the friction pair has the function of storing oil and reducing the contact area, thus reducing the friction coefficient. After the friction plate is set between the friction pairs, due to the result of relative friction, the relative displacement of the friction pair will be less than the relative displacement without the friction plate, which reduces the length of the required displacement of the support and saves the manufacturing size of the support. The displacement is completed according to the minimum friction coefficient of the double-sided plate. The friction pair and the friction plate are selected with different materials of different hardness and strength to reduce the material viscosity effect caused by time, reduce the indentation on the edge of the friction pair formed by long-term action, and reduce the resistance during displacement.

[0023] (4) This invention reduces the amplitude of the wave by changing the spectrum of the force and controlling the generation of resonance: the support reduces the lateral and vertical forces, eliminates the hidden dangers of jumping, hard collision, long external force spectrum period and large external force spectrum amplitude in the process of vibration reduction and isolation, and has the function of bearing multiple periodic forces.

[0024] (5) The performance parameters of the support can be changed by replacing the components inside the support; the direction of the displacement can be controlled after the circular plane can be changed to a square or a rectangle; the displacement can be stably reset after the circular plane is changed to a circular crown surface or a circular arc surface; the support has a wide range of applications, strong performance targeting, and stable applicability, and does not restrict the size of the support, nor does it have any special restrictions on the height and diameter ratio of the support; the support is durable and detectable, saving manpower, material resources, financial resources and time, and there is no need to worry about the service life of the support during use;

[0025] (6) The materials used in this support are highly selectable and have advantages such as durability, stability, reliability, wide applicability and sustainable development. The space inside the support is sealed with bushing components and thin plastic materials to prevent water inlet from freezing and to ensure that the support function is not lost due to environmental changes. The support uses the functions of vibration control, damping and isolation, and vibration reduction and isolation to slow down the thermal expansion and contraction effect of the supported object and effectively eliminate the planar torsional effect of the supported object under horizontal action.

[0026] (7) The function of the vertical sliding member at the vertical cylindrical end of the moving component of the support and the upper end connecting member of the moving component is: to adjust the uneven stress between the moving component and the annular moving component at the top of the support by lowering the cover plate of the circular hole at the top of the support, to avoid additional stress at the vertical cylindrical end of the moving component when the annular moving component at the top of the support is tilted, and to give full play to the expected functions of the vertical deformation component, the moving component and the annular moving component at the top of the support.

[0050] The support bottom component 1 is a plane or a concave spherical crown-shaped surface; when the support bottom component 1 is a plane, the moving component 2, the annular control component 3, the annular moving component 4, and the support top moving component 5 are all planes respectively; when the support bottom component 1 is a concave spherical crown-shaped surface, the moving component 2, the annular control component 3, the annular moving component 4, and the support top moving component 5 are all concave spherical crown-shaped surfaces respectively; that is, when the support is a concave spherical crown-shaped surface, the contact surface between the support bottom component 1 and the moving component 2 is a concave spherical crown-shaped surface, the contact surface between the moving component 2 and the annular control component 3 is a concave spherical crown-shaped surface, the contact surface between the annular control component 3 and the annular moving component 4 is a concave spherical crown-shaped surface, and the contact surface between the annular moving component 5 is a concave spherical crown-shaped surface.

According to the functional requirements of the support: the planar displacement surface of the circular support is changed to a circular concave spherical cap-shaped displacement surface support. The movable component 2 is a concave spherical cap-shaped curved surface, the annular control component 3 is a concave hollow cone, the annular movable component 4 is a concave hollow cone, and the annular component 5 at the top of the support is a concave hollow cone.

Among them, the maximum arc displacement Rmax of the moving component 2 relative to the ring control component 3 is a function of the oscillation of the moving component 2 according to R1 caused by vibration or vibration, the power density S0, the frequency ωg of vibration or vibration, the damping coefficient ζ of the support, the friction coefficient µ of the support, the frequency ω of the support, and the stiffness of the support. Due to the particularity of each vibration or vibration, the maximum arc displacement Rmax is not uniform, forming a series of support models for the product.The space clearance between the bottom edge of the moving component 2 and the inner side of the support bottom component 1 and the ring control component 3 should meet the following: the maximum circular arc displacement Rmax of the moving component 2 relative to the support bottom component 1 and the ring control component 3 + the sum of the radial arc length of the space volume required by the lateral deformation component. Among them, the maximum circular arc displacement Rmax of the moving component 2 relative to the support bottom component 1 and the ring control component 3 is a function of the oscillation of the moving component 2 according to R1 caused by vibration or vibration, the power density S0, the frequency of vibration or vibration ωg, the damping coefficient ζ of the support, the friction coefficient µ of the support, the frequency ω of the support, and the stiffness of the support. Due to the difference in vibration or vibration, the maximum circular arc displacement Rmax of the support is not uniform, forming a series of support models for the product. The inner side of the free end formed around the central circular hole of the annular control component 3 is supported by the moving component 2. When in its original position, the radial support arc length f(r) of the moving component 2 in the horizontal inner region around the free end of the central circular hole of the annular control component 3 is L. When the moving component 2 has an arc displacement relative to the annular control component 3 during vibration, f(r) is a variable. The range of f(r) is: 0~L + the sum of the maximum radial arc displacement Rmax of the moving component 2 relative to the annular control component 3. The outward radial arc length from the outer edge of the circular step column on the bottom disk of the moving component 2 to the edge of the bottom disk is = L + the sum of the maximum arc displacement Rmax of the moving component 2 relative to the annular control component 3 + the radial arc length of the space volume required by the transverse deformation component, and enables the moving component 2, the annular moving component 4, and the top annular component 5 of the support to have a reset function along the curved surface.

[0051] There is a space gap between the inner ring edge of the ring control component 3 and the outer edge of the vertical circular step column of the moving component 2; the space gap is the maximum horizontal displacement Xmax of the moving component 2 relative to the ring control component 3, and is also the radial length of the space volume required by the transverse deformation component; the maximum horizontal displacement Xmax of the moving component 2 relative to the ring control component 3 is related to the power density S0 of the vibration or vibration, the frequency ωg of the vibration or vibration, the damping coefficient ζ of the support, the friction coefficient µ of the support, the frequency ω of the support, and the stiffness of the support; therefore, the difference in vibration or vibration makes the maximum horizontal displacement Xmax of the support often inconsistent.

[0052] The space distance between the inner ring edge of the ring control component 3 and the outer edge of the vertical circular step column on the bottom disk of the moving component 2 should satisfy: the sum of the maximum horizontal displacement Xmax of the moving component 2 relative to the ring control component 3 and the radial length of the space volume required by the transverse deformation component. The maximum horizontal displacement Xmax of the moving component 2 relative to the ring control component 3 is a function of the power density S0 of the vibration or vibration, the frequency ωg of the vibration or vibration, the damping coefficient ζ of the support, the friction coefficient µ of the support, the frequency ω of the support, and the stiffness of the support. Due to the particularity of each vibration or vibration, the maximum horizontal displacement Xmax is not uniform, forming a series of support models. The space clearance between the bottom edge of the moving component 2 and the inner side of the support bottom component 1 and the ring control component 3 should meet the following: the maximum horizontal displacement Xmax of the moving component 2 relative to the support bottom component 1 and the ring control component 3 plus the radial length of the space volume required by the transverse deformation component. Among them, the maximum horizontal displacement Xmax of the moving component 2 relative to the support bottom component 1 and the ring control component 3 is a function of the power density S0 of the vibration or vibration, the frequency ωg of the vibration or vibration, the damping coefficient ζ of the support, the friction coefficient µ of the support, the frequency ω of the support, and the stiffness of the support. Due to the differences in vibration or vibration, the maximum horizontal displacement Xmax of the support is not uniform, forming a series of support models. The inner side of the free end formed around the central circular hole of the annular control component 3 is supported by the moving component 2. When in place, the radial support length f(r) of the moving component 2 in the horizontal inner region around the free end of the central circular hole of the annular control component 3 is L. When there is horizontal displacement of the moving component 2 relative to the annular control component 3 during vibration, f(r) is a variable.
