Abstract
Optimal Damping Ratio (OPR) of a suspension system was existed and proved by linear vibration model on suspension system of multi-wheel vehicle. The theory of semi-active suspension was established by the OPR control policy of statistic meaning. Simulation of suspension dynamics of a full tracked vehicle was researched using visual mechanics method based on multi-body dynamics theory with the co-simulation technology of mechanical system and control system. Dynamics characteristic comparison of the tracked vehicle equipped with passive and semi-active suspension was done by the co-simulation method. Finally, a conclusion is drawn from the simulation results that ride-comfort of tracked vehicles can be improved and vibration acceleration can be decreased obviously if the OPR control semi-active suspension is used.
