Simulation and evaluation of the vehicle steering wheel angle pulse input test based on ADAMS

The vehicle's steering wheel angle pulse input performance is 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 the vehicle for example, in ADAMS software, vehicle dynamics model is built. According to GB/T6323.3-94 standards, the steering wheel angle pulse input virtual test is 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.
