Abstract

In order to improve the vibration reduction performance of a special vehicle, a mathematical model with 13 DOF of the special vehicle is established by reasonable simplification. The vehicle dynamics simulation model is established based on the multi-body system dynamics software Simpack; the model of hydro-pneumatic suspension is established in AMEsim; a random road excitation model is established in Simulink. Through multi-software co-simulation, the vibration reduction performance of ipsilateral coupled hydro-pneumatic suspension and hybrid connected hydro-pneumatic suspension of a special vehicle is compared and analyzed. The results show that the hybrid connected hydro-pneumatic suspension system can improve the driving stability of the vehicle and improve the anti-roll and anti-pitch ability.
