| Abstract: | By using multi-body dynamics technique,a full vehicle nonlinear model for a passenger car is set up,which takes into consideration the detailed geometric structural parameters of steering system and the nonlinear characteristics of rubber bushing and damper,and uses a Magic Formula model for tire.The simulation models built are validated with various tests on a real vehicle with its handling stability analyzed.The simulation result shows that the nonlinear multi-body model has a high accuracy. |
