Adaptive equal-rigidity vibration isolator based on electric-damping three-direction decoupling

Abstract

The invention discloses an adaptive equal-rigidity vibration isolator based on electric-damping three-direction decoupling and mainly relates to the field of three-direction vibration isolation of high-end, precise and sophisticated electronic equipment. The vibration isolator comprises a vibration isolating shell, a three-direction moving block, a vibration isolating link and five electric damping systems, wherein the electric damping systems are arranged between the vibration isolating shell and the three-direction moving block; two electric damping systems, two electric damping systems and one electric damping system are respectively arranged in three directions, namely an X direction, a Y direction and a Z direction, of the three-direction moving block, and the five electric damping systems are independent of one another so as to achieve three-direction decoupling. The adaptive equal-rigidity vibration isolator based on electric-damping three-direction decoupling, disclosed by the invention, has the advantages that the structure is reasonable, rigidity decoupling is realized by adopting electric damping, and the rigidity of each of the three directions is adjustable.

Description

technical field [0001] The invention mainly relates to the field of three-way vibration isolation of high-end, high-precision and cutting-edge electronic equipment, in particular to an adaptive equal-stiffness vibration isolator based on electrodynamic damping three-way decoupling. Background technique [0002] High-end, sophisticated electronic equipment usually places high demands on vibration isolation equipment. In traditional technology, the vibration isolators used in electronic equipment mainly include wire rope vibration isolators, rubber vibration isolators, metal spring vibration isolators, etc., and they all have some common characteristics: the stiffness in the Z direction is much greater than the stiffness in the X and Y directions; The stiffness in one direction cannot be adjusted actively. In the prior art, the document (Patent No.: 201210449640.1) discloses a three-way equal stiffness vibration isolator, which successfully achieves the equal stiffness requir...
