Problems solved by technology

The existing widely used vibration isolators are mainly metal vibration isolators. Although metal vibration isolators have good stiffness characteristics, they usually have small damping. More importantly, the damping force of metal vibration isolators cannot be actively adjusted.

Abstract

The invention discloses a constant-rigidity vibration isolator with active variable damping of connecting rod movement, which belongs to the field of damping vibration isolators. It consists of a casing, an upper bottom plate and a lower bottom plate, and a cylindrical guide rod fixed on the lower bottom plate at the axial position of the casing at the lower end; the main vibration isolation spring, the lower sliding ring, the fixed The ring, the upper sliding ring and the lifting sleeve; the two sides of the upper sliding ring and the lower sliding ring are respectively connected by a connecting rod spring variable damping structure A and a connecting rod spring variable damping structure B; the connecting rod spring variable damping structure A includes a damping plate A, the upper link A, the lower link A and the metal coil spring A; the link spring variable damping structure B includes the damping plate B, the upper link B, the lower link B and the metal coil spring B. The invention is a variable damping vibration isolator which has a simple and reasonable structure, actively realizes positive correlation between damping and excitation force by means of connecting rod movement, and damping change does not affect system stiffness.

Description

technical field [0001] The invention mainly relates to the field of damping vibration isolators, in particular to a constant-rigidity vibration isolator of active variable damping with connecting rod movement. Background technique [0002] With the development of the electronics industry, the requirements for vibration isolation of electronic equipment are getting higher and higher. The existing widely used vibration isolators are mainly metal vibration isolators. Although metal vibration isolators have good stiffness characteristics, they usually have small damping. More importantly, the damping force of metal vibration isolators cannot be actively adjusted. . Therefore, it is of great practical value to design a vibration isolator whose damping force is positively correlated with the exciting force. Contents of the invention [0003] The technical problem to be solved by the present invention is: Aiming at the technical problems existing in the prior art, the present i...
