The nonlinear dynamics simulation model of a tracked vehicle is built using multi-body dynamics software. The accuracy and validity of the model are tested and evaluated by comparing the simulation value with the design value and the simulation data with the experimental data. It is proved that the established dynamic model is effective. The vibration characteristics of the vehicle are simulated and analyzed on four tyical roads at different speeds. It shows that multi-body dynamics simulation model of the vehicle ride comfort can achieve high accuracy, the model and modeling method can provide an effective way for the design of the running system and the dynamic analysis of the tracked vehicle.
