Steady-State Response of the System which Consists of Shear Loading Rubber Isolators and a Mass

Abstract

In order to find the mechanism of the steady-state response of a system which consists of shear loading rubber isolators and a mass, experiments for the steady-state frequency response of the system and dynamic tests for the rubber vibration isolators are conducted under the various conditions of ambient temperature and strain amplitude, and the results are considered and discussed. As a result, it is found that the amplitude and temperature response of the system interact via the temperature-dependent dynamic properties and the internal heat-generation rate of the vibrating rubber isolator. On the basis of this result, a new method for the analysis of the steady-state response of the system is presented. Using this method, the influence of system parameters on the response is also discussed.
