Mechanical Modeling Of High-Damping Rubber Dampers Using Nonlinear System Identification

摘要

This paper addresses the use of nonlinear system identification in the mechanical modeling of a high-damping rubber damper. The model consists of one linear spring, two linear dashpots, and one nonlinear spring in order to represent the amplitude-and frequency-dependent properties of the damper. The mechanical properties of the linear spring and two dashpots are determined from the test results by using the nonlinear system identification technique. The restoring force characteristics of the nonlinear spring is formulated by incorporating a versatile hysteresis model.
