Vibration Characteristics of Rubber Vibration Isolators of Vehicle : Analysis of Nonlinear Vibration Response

Abstract

We have already proposed the analytical method for analyzing nonlinear vibrational properties of rubber, using experimental results from dynamic hysteresis characteristics tests. These tests are performed with rubber vibration isolators used in automobiles. Using the above method, we describe here a method for analyzing nonlinear vibration response properties of rubber in relation to frequency and amplitude of displacement. We can prove the accuracy of this method by directly comparing experimental results with the analytical ones of the dynamic response of a system, with one degree of freedom and modeling the rubber as a spring.
