Abstract For studying the performance of hydro-pneumatic spring and hydraulic buffer and their effect on a suspension system, the dynamics model of single-wheel suspension system of a tracked vehicle was established by RecurDyn. Based on the vehicle dynamic and the crash theory, the cushioning and absorbing of the crash energy of the suspension system were studied. The results show that a dynamics model of single-wheel suspension system used for simulating is valuable for studying the properties of the suspension system, which can replace a whole vehicle’s simulation to some extent. The hydro-pneumatic suspension system has non-linear and large damping properties which have a strong ability to cushion and absorb the crash energy in a large amplitude vibration.
