Integrated composite vibration isolator based on metal rubber and working method thereof

Abstract

The invention relates to an integrated composite vibration isolator based on metal rubber and a working method thereof. The composite vibration isolator comprises a cylindrical outer cover shell, an upper-layer vibration isolation structure and a lower-layer vibration isolation structure, wherein the upper-layer vibration isolation structure and the lower-layer vibration isolation structure are arranged in the outer cover shell; and the upper-layer vibration isolation structure comprises a fixed upper shell, a plurality of bolts arranged on the fixed upper shell in an array manner and metal rubber elements arranged on the bolts in a penetrating manner, and the lower-layer vibration isolation structure comprises a fixed lower shell, a base and a lower-layer high-damping material layer located between the fixed lower shell and the base. The metal rubber element is tightly pressed between the fixed lower shell and the fixed upper shell, a load-bearing spring pre-pressed between the fixed lower shell and the fixed upper shell is arranged in the middle between the fixed lower shell and the fixed upper shell, and the upper part of the fixed upper shell extends out of an upper opening of the outer cover shell and is connected with a load-bearing plate and an upper-layer high-damping material layer which are stacked; and according to the composite vibration isolator, the defect that a metal vibration isolator is poor in low-frequency vibration absorption performance is overcome, meanwhile, absorption of horizontal vibration is enhanced, and the impact resistance is improved.

Description

Technical field: [0001] The invention relates to an integrated composite vibration isolator based on metal rubber and a working method thereof, belonging to the technical field of vibration isolation of electrical equipment. Background technique: [0002] With the progress of society, the environmental requirements for equipment use and the accuracy of instruments are getting higher and higher. Environmental vibration is an important factor affecting the stability of instrument performance. Therefore, the absorption of environmental vibration is an important measure to improve instrument performance. The method of installing vibration isolators between the equipment and the base is the most widely used. [0003] At present, the vibration isolators commonly used in electronic equipment in the market include air spring vibration isolators, rubber vibration isolators and metal vibration isolators. Among them, the natural frequency of air vibration isolators is close to 1Hz, whi...
