Abstract:A vehicle dynamics model was established based on the multi body dynamics theory and applied to the virtual handling stability test.The files of pylon course slalom rood and lemniscates curve road were built by using event builder,and respectively used as the driver files of pylon course slalom virtual test and steering efforts virtual test.According to the national standard of vehicle handling stability,several virtual test cases including the steering wheel angle step input,steering wheel angle pulse input,turning back performance,steady state turning back,pylon course slalom and steering efforts were carried out,then the performance indicators of handling stability were scored and evaluated.The method proposed provides a reference to the virtual test of vehicle handling stability.
