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.
