Development of MRF Damper Modelling and Validation of MRF Damper Test

Abstract

Active/semi-active suspension systems are getting widely accepted for their potential to improve ride comfort of passenger cars. In this work, the paper develops the model of magnetorheological fluid (MRF) damper to describe the hysteretic behaviors and damper characteristic. It used the modeling-after-test method to establish an accurate MRF-damper model, and the MRF damper model is consecutive adjustable. The linear interpolation technique is used to derive an equivalent MRF damper model. The simulation results of the developed MRF model are verified using MTS damper test. It is shown that the built MRF model matches the test data very well.
