Abstract

The invention discloses a vibration isolator. A positive stiffness component, magnetic damping components and magnetic negative stiffness components of the vibration isolator are arranged between a base board and a middle board in parallel; the magnetic damping components and the magnetic negative stiffness components are evenly arranged on the edge of the base board in the circumferential direction; one swing mechanism penetrates through the center of the positive stiffness component to be connected with the positive stiffness component in series; the swing mechanism isolates vibration in thehorizontal direction through low horizontal stiffness of a flexible swing rod; and each magnetic damping component and each magnetic negative stiffness component are each divided into two coaxial parts which are fixedly connected with the base board and the middle board separately and generate action through electromagnetic force, and no mechanical contact or abrasion is generated. The vibrationisolator capable of achieving horizontal decoupling can achieve high static stiffness and low dynamic stiffness in the vertical direction and vibration decoupling in the horizontal direction and the vertical direction.

Description

technical field [0001] The invention relates to the technical field of mechanical engineering vibration isolation and vibration reduction, in particular to a vibration isolator capable of realizing horizontal decoupling. Background technique [0002] With the development of science and technology, the precision requirements of manufacturing and measurement are getting higher and higher, and people's requirements for environmental vibration and noise are also getting higher and higher. However, the sources of vibration are more and more complex, and the objective requirements are More advanced vibration control technology. However, due to the limitation of the bearing capacity on the support stiffness of the existing vibration isolators, it is difficult to reduce the natural frequency and meet the requirements of ultra-low frequency vibration isolation. Contents of the invention [0003] The purpose of the present invention is to provide a vibration isolator that can achie...
