Abstract

This paper presents a new theoretical method for the dynamic analysis of a vehicle coupling the longitudinal, lateral and roll motions. First, the nonlinear full-vehicle model is modelled in the global coordinate system and vehicle coordinate system, respectively. Second, the instantaneous screws are applied to represent the cornering forces acting on the vehicle system and describe the kinematic and static relations of the full-vehicle model. Based on these relations the generalize coordinates and forces are determined for the dynamic analysis. The dynamic equations are derived by the using of Lagrangian formula. Finally, two numerical examples are illustrated for the validity of the proposed method. Compared with Software Carsim it is shown that the theoretical method is effective for the dynamic analysis of a vehicle.
