Study on the dynamic model of magnetorheological elastomer vibration isolator

Abstract

Magnetorheological elastomers vibration isolator is a new controllable device, which shows a widely application in active or semi-active control. In fact, it is very important to constitute a precise dynamic model of the MR elastomer isolator, which gives help for design the control strategy and control method, and achieve good control effectiveness. At present the models is convenient to analyze and calculate the change of MR elastomer's properties, but it can not put up the saturation of the stiffness and the parameter of model is magnetic field strength which adding the complexity of engineering application. In this paper, a phenomenon model was constituted to describe the dynamic performance of the MR elastomer vibration isolator. Using the test results of the isolator, parameters of the model were achieved. By comparing the simulation results with the test results, we can find that they tally well with each other, which validates the dynamic model.
