Modeling and Simulation of Non-independent Suspension Vehicle

In this paper, six DOF model has been established for non-independent suspension vehicle with Robertson - Widenborg multi-body dynamics method. On this basis, Yaw velocity gain of a heavy vehicle was simulated by Matlab. The simulation results verified the model is reasonable. After further simulation, it indicates the model has theory significant for researching the handling and stability and designing suspension system and the structure layout of this type vehicle.
