Abstract

The invention discloses a three-direction decoupled equal-rigidity vibration isolator based on integration of air damping and electric damping and mainly relates to the field of three-direction vibration isolation for high-end electronic equipment. The three-direction decoupled equal-rigidity vibration isolator comprises a shell, a suspension block, a vibration table, a connection rod, balls, an air damping system and an electric damping system. In the X-direction, Y-direction and Z-direction, the air damping system is mounted in at least one of the directions, and the electric damping system is mounted in at least one of the directions. Flexural rigidities of the air damping system and the electric damping system is zero, namely rigidities in the X-direction, the Y-direction and the Z-direction are decoupled. The three-direction decoupled equal-rigidity vibration isolator based on integration of air damping and electric damping has the advantages of reasonable structure, decoupled rigidity and better vibration isolation performance.

Description

technical field [0001] The invention mainly relates to the field of three-way vibration isolation of high-end electronic equipment, in particular to a vibration isolator with equal stiffness based on three-way decoupling combined with air flotation and electric power. Background technique [0002] In traditional technology, metal vibration isolators, wire rope vibration isolators, rubber vibration isolators, harmonic-free damping vibration isolators and other vibration isolation equipment are usually used for vibration isolation protection of high-end electronic equipment. These vibration isolation equipment have a common The defect is that the stiffness of the three vibration isolation directions is quite different, so it is easy to cause the failure of electronic equipment. [0003] In the prior art, the document with the patent number 201210449640.1 discloses a metal vibration isolator with equal stiffness in three directions, which realizes vibration isolation with equal...
