Adjustable double-layer metal rubber damping vibration absorber and working method thereof

Abstract

The invention relates to an adjustable double-layer metal rubber damping vibration absorber and working method thereof. The vibration absorber comprises a base seat and an outer shell fixedly connected to the base seat, wherein an end cover, an upper fixing support and a lower fixing support are sequentially arranged between the inner top surface of the outer shell and the base seat from top to bottom. An upper spring assembly is connected between the end cover and the upper fixing support, metal rubber damping elements are arranged between the upper fixing support and the lower fixing support, and a lower spring assembly is connected between the lower fixing support and the base seat. According to the adjustable double-layer metal rubber damping vibration absorber and working method thereof, the vibration absorber is reasonable in structure, the composite structure of the metal rubber and the springs is adopted, the rigidity of the vibration absorber is adjusted mainly through the springs, and the metal rubber damping element not only increases the damping of the vibration absorber, but also can be applied to various working conditions. Through the combination of the metal rubberand the springs, the overall rigidity and the damping of the vibration absorber can be adjusted to the most appropriate performance parameter interval in practical application, the comprehensive performance of the vibration absorber is improved, and a good vibration reduction effect is achieved.

Description

Technical field: [0001] The invention relates to an adjustable double-layer metal rubber damping shock absorber and its working method. Background technique: [0002] With the development of industrial technologies such as aerospace, marine chemical industry and nuclear energy equipment, the requirements for vibration reduction and buffering of equipment are increasing. The existing vibration reduction and buffering methods generally use rubber materials or vibration reduction devices. However, traditional rubber materials are difficult to meet the technical requirements in complex environments such as high and low temperature, heavy load impact, etc., and the traditional vibration damping device has the following shortcomings: (1) The working temperature range of the traditional rubber vibration damping device is narrow, and the rubber It is easy to chemically react with ozone and light to cause aging, and it will become hard and brittle at low temperatures to partially cra...
