Problems solved by technology

However, due to the very complex conditions of the external environment, the external force, especially the impact force, is also extremely complex. Although some vibration isolators in the prior art have the effect of variable damping force and some have the effect of variable stiffness, the damping force and Changes in stiffness have no correlation

Abstract

The invention discloses an anti-shock vibration isolator with synchronous adjustment of damping and stiffness, which belongs to the field of vibration isolators. It includes the shell, the upper cover and the lower cover fixedly installed on the upper and lower ends of the shell, the guide column fixedly installed on the shell, the lifting sleeve slidingly installed on the guide column, and the lifting sleeve fixedly installed on the lifting sleeve. Vibration isolation platform; a variable damping module is slidingly installed on the guide column, and a variable stiffness module A and a variable stiffness module B symmetrical to the guide column are installed inside the shell; the variable damping module includes a pressure plate A, a pressure plate B, a metal anti-corrosion A tension-compression coil spring, a connecting rod A, a connecting rod C, a connecting rod B and a connecting rod D, and two symmetrically installed damping blocks. The invention is an anti-shock vibration isolator with simple and reasonable structure, whose stiffness and damping increase synchronously with the increase of external impact force.

Description

technical field [0001] The invention mainly relates to the field of vibration isolators, in particular to an anti-shock vibration isolator with synchronous adjustment of damping and stiffness. Background technique [0002] Vibration isolators play a very important role in the use and transportation of electronic products, because they can absorb energy well and play the role of vibration isolation protection. However, due to the very complex conditions of the external environment, the external force, especially the impact force, is also extremely complex. Although some vibration isolators in the prior art have the effect of variable damping force and some have the effect of variable stiffness, the damping force and None of the changes in stiffness are relevant. Therefore, it is of great significance to design a vibration isolator whose damping force and stiffness can be adjusted synchronously.
