Steering Wheel Angle Pulse Input Simulation and Evaluation of a Car Based on ADAMS

Vehicle’s steering wheel angle pulse input performance was an representative test of handling and stability, it characterizes vehicle’s handling and stability by the transient response of the steering wheel angle pulse input. Taking a car for example, in the ADAMS software, vehicle dynamics model was established. According to GB/T6323.3—94 standards, the steering wheel angle pulse input virtual test was carried out, and then applied the QC/T 480—1999 limit vehicle handling and stability indices and assessment methods to evaluate the results of the simulation, the result is 66.2247 points, among that, the resonant peak level is 36.0973 points, indicating the vehicle's steering transient response ability is poor, should be improved.
