Integrated quasi-zero stiffness vibration isolation buffering element and vibration isolation buffering assembly

Abstract

The invention provides a miniaturized and integrated quasi-zero stiffness vibration isolation buffering element. The miniaturized and integrated quasi-zero stiffness vibration isolation buffering element comprises a pressure-bearing seat, a base and bent rod bodies; a first through hole which is through up and down is formed in the pressure-bearing seat; a second through hole coaxial with the first through hole of the pressure-bearing seat is formed in the base; each bent rod body comprises an inclined section and a vertical section; each vertical section is vertically arranged, one end of each inclined section is fixedly connected with the pressure-bearing seat into a whole, and the other end of each inclined section is fixedly connected with the upper end of the corresponding vertical section into a whole; the included angle between the vertical sections and the inclined sections in a non-working state is an obtuse angle; and the pressure bearing seat, the base and the plurality of bent rod bodies are of an integrally-formed structure. According to the integrated quasi-zero-stiffness vibration isolation buffering element, an existing quasi-zero-stiffness vibration isolation element does not need to be hinged or assembled, the structure is simple, machining and manufacturing are easy, the using effect cannot be affected by any friction force generated by hinging, and the application range is greatly widened.

Description

technical field [0001] The invention belongs to the field of low-frequency or ultra-low-frequency vibration isolators, and in particular relates to an integrated quasi-zero stiffness vibration-isolation buffer element and a vibration-isolation buffer assembly. Background technique [0002] The quasi-zero-stiffness shock absorber is to connect the negative-stiffness element in parallel with the positive-stiffness original, so as to realize the zero-stiffness characteristic at the static equilibrium position. Compared with traditional linear vibration isolators (the effective vibration isolation frequency is greater than times the natural frequency, and the vibration isolation frequency range is narrow), the quasi-zero stiffness vibration isolator is proposed to achieve the characteristics of high static stiffness and low dynamic stiffness, while having a large bearing capacity, the structural deformation is small, and the vibration isolation frequency band is widened .
