Analysis on the Vibration Control of Tracked Vehicle Suspension System Using Magnetorheological Fluid Damper

A simulation analysis of the semi-active control of tracked vehicle suspension system was given using magnetorheological fluid dampers.After formulating the equations of motion for suspension system considering two degrees of freedom,the control effectiveness of full state feedback control of LQR was calculated with the input of six measured road surface excitations.Simulation of semi-active control utilizing magnetorheological fluid damper with limited optimal Hrovat control algorithm and the semi-active control strategies proposed was carried out,and the results of the two control methods were compared.The effectiveness of semi-active control force tracking active control force was conducted and the analysis of active force was given,showing why semi-active control can replace active control.Simulation results show that magnetorheological fluid damper in the semi-active vibration control of suspension system of tracked vehicle is feasible.
