    Abstract
  • Multi-body dynamics, relative coordinates and graph theory are combined to analyze the structure of a vehicle suspension. The dynamic equations of the left front suspension system are derived for modeling. First, The pure tire theory model is used as the input criteria of the suspension multibody system dynamic model in order to simulate the suspension K&C characteristics test. Then, it is important to verify the accuracy of this model by comparing and analyzing the experimental data and simulation results. The results show that the model has high precision and can predict the performance of the vehicle. It also provides a new solution for the vehicle dynamic modeling.
