Anti-collapse multi-layer metal corrugated pipe solid-liquid mixed vibration isolator

Abstract

The invention relates to an anti-collapse multi-layer metal corrugated pipe solid-liquid mixed vibration isolator. The vibration isolator comprises a corrugated pipe container, hydraulic oil, compressible elastic rubber units and circular sticking patches, wherein the corrugated pipe container is loaded with a solid-liquid mixed medium composed of the hydraulic oil and the compressible elastic rubber units; the compressible elastic rubber units can be filled with air, pressurized gas or be vacuumized; and the circular sticking patches are welded to the top end and the bottom end of the corrugated pipe container to seal the corrugated pipe container. The vibration isolator has good vibration isolation performance and can effectively improve the anti-collapse capacity of structures. The vibration isolation effect can be adjusted by changing the number of the compressible elastic rubber units, and meanwhile the problem of oil leakage is avoided by adopting multiple layers of corrugated pipes. Alloy materials used for making the corrugated pipes has the multiple advantages of oil resistivity, corrosion resistance, heat resistance, lowest aging and the like.

Description

technical field [0001] The invention relates to an anti-collapse multilayer metal bellows solid-liquid mixing vibration isolator, which belongs to the technical field of hydraulic vibration isolation and anti-collapse. Background technique [0002] Vibration control technology is mainly divided into three categories: passive control, semi-active control and active control. In actual engineering, compared with the other two schemes, passive control has been widely studied and applied because of its advantages of simplicity, convenience and low cost. [0003] In recent years, the liquid-solid mixed medium vibration isolator has also received some attention as a new vibration control method, especially in low-frequency heavy-load vibration isolation, which has obvious advantages. The traditional liquid-solid hybrid vibration isolator is composed of hydraulic cylinder, hydraulic oil, elastic unit and piston, etc. It has good vibration isolation performance, but there are also p...

Problems solved by technology

[0005] In order to overcome the problems of short fatigue life, unit aging, oil leakage and other problems existing in existing vibration isolators, the purpose of the present invention is to provide a multi-layer metal bellows type solid-liquid mixing vibration isolator. On the basis of vibrators, the alloy bellows structure is introduced, and the top and bottom ends of the bellows container are welded with circular patch seals to solve the problem of oil leakage.

This vibration isolator has the advantages of good vibration isolation performance of traditional vibration isolators, and at the same time solves the problems of traditional vibration isolators such as short fatigue life, rubber unit aging, oil leakage, etc., and improves the collapse resistance of the structure
