Abstract

The invention discloses an equal-stiffness vibration isolator based on air floatation and magnetic floatation combination three-directional decoupling, and mainly relates to the field of three-directional equal-stiffness vibration isolation of electronic equipment. The equal-stiffness vibration isolator comprises a mounting shell, a suspension block, a connecting rod, an electronic platform, an air floatation damping system and a magnetic floatation damping system, wherein the magnetic floatation damping system is assembled in at least one of an X direction, a Y direction and a Z direction; the air floatation damping system is assembled in at least one of the X direction, the Y direction and the Z direction; and the anti-bending stiffness of the air floatation damping system and the anti-bending stiffness of the magnetic floatation damping system are zero, namely, stiffness decoupling in the X direction, the Y direction and the Z direction is implemented. The equal-stiffness vibration isolator based on air floatation and magnetic floatation combination three-directional decoupling is reasonable in structure and has a three-directional stiffness decoupling effect.

Description

technical field [0001] The invention mainly relates to the field of three-way constant-stiffness vibration isolation of electronic equipment, in particular to a three-way decoupling equal-stiffness vibration isolator based on the combination of air floatation and magnetic floatation. Background technique [0002] For high-end, high-precision, and cutting-edge electronic instruments, it is usually required to perform three-way equal-stiffness vibration isolation protection. Traditional vibration isolation equipment mainly includes wire rope vibration isolators, rubber vibration isolators, metal spring vibration isolators, non-harmonic peak damping vibration isolators, etc. These vibration isolators have a common feature: the stiffness in the Z direction is much greater than that in the X, Y direction stiffness. Therefore, it is difficult for them to meet the vibration isolation requirements of electronic equipment with equal stiffness in three directions. [0003] In the pr...
