Simulation for Handing and Stability of Vehicle Based on SimulationX
To build a dynamic vehicle model is the most important work in the field of digital virtual prototyping technology for studying on its handing and stability. A 54 degrees of freedom multi-body vehicle model with tire, suspension and steering was established in SimulationX software. Time domain response under steering wheel step input and frequency response under steering wheel sinusoidal input were obtained, the changing trend of indicators with different speeds was presented, the handing and stability of vehicle model was evaluated, also the impact of caster angle and kingpin inclination to handing and stability was analyzed. The simulation results were consistent with theoretical analysis and actual situation.
