Nonlinear vibrations of vehicle suspension systems with magnetorheological dampers

Abstract

The paper is devoted to analyze nonlinear vibrations of vehicle suspension systems with magnetorheological (MR) dampers. With two reasonable assumptions and some appropriate formulations, in light of the results of single-degree-of-freedom isolation systems with MR dampers, the solutions of harmonic responses of quarter car suspension systems with MR dampers are presented. And the solutions of sprung and unsprung transmittances for the system are also given. Numerical simulations verified the resulting solutions of theoretical analysis.
