Efficient driven vibration insulation and reduction platform imitating physiological structure of head of woodpecker

Abstract

The invention discloses an efficient driven vibration insulation and reduction platform imitating the physiological structure of the head of a woodpecker. The efficient driven vibration insulation and reduction platform comprises a driven vibration-reduction assembly, a variable-stiffness various-damping air spring assembly, a combination bearing platform and an outer frame, the driven vibration-reduction assembly comprises a hard rubber pad and a cutting type viscoelastic damper, the variable-stiffness various-damping air spring assembly comprises two or more than two double-air-chamber air springs which are symmetrically distributed along a machine base, the combination bearing platform comprises a top board, a bottom board and side boards, wherein the top board, the bottom board and the side boards are made of steel boards, insulation layers are arranged among the top board, the bottom board and the side boards, and the outer frame is symmetrically arranged on two sides of the machine base. The efficient driven vibration insulation and reduction platform imitating the physiological structure of the head of the woodpecker has no acting part and is low in energy consumption. Compared with a vibration-reduction platform under driving control, the efficient driven vibration insulation and reduction platform can greatly lower manufacturing cost and operation cost, save energy, and be economical and practical.

Description

technical field [0001] The present invention relates to the fields of vibration control technology and bionic technology, in particular to a high-efficiency passive isolation and vibration reduction platform imitating the physiological structure of a woodpecker head. Background technique [0002] In recent years, due to the continuous advancement of technology and industry, high-precision systems such as high-speed rotating machinery, electronic equipment, high-efficiency and high-precision machining, and micromechanics have reached extremely stringent requirements for vibration isolation systems. Various environmental vibrations and mechanical shocks have become important factors that limit the improvement of machining accuracy or working accuracy of various high-precision systems. At present, in precision systems, air springs are still used as passive or semi-active vibration isolation and damping systems as the main vibration isolation components. This vibration isolation...

AI Technical Summary

Problems solved by technology

Therefore, the vibration damping platform belongs to the field of active control and its application is limited to precision control systems, so it is difficult to apply it to various other mechanical equipment.

[0005] To sum up, it can be seen that the high-precision system vibration isolation platforms that have been developed so far all adopt active or semi-active vibration control technology mainly based on active vibration reduction control technology. Algorithm, not only the structure is complex, but also the cost is high, the cycle is long, and the installation and debugging are relatively difficult for passive vibration control technology
