| Abstract: | The characteristics and application range of all kinds of commonly used tire models are analyzed. According to the requirements of automobile dynamics research, a tire dynamic model is conducted by adopting the ＂magic formula＂ in Matlab/Simulink. Simulation analysis is carried out as to tire characteristics such as tire force and skid rate, vertical force, side force, self-aligning torque and skid rate, slip angle, and vertical load. The results indicate that the tire dynamic model established using the ＂magic formula＂ is able to simulate tire dynamic characteristics closely and fulfill the research requirements with regard to automobile dynamics. |
| Keywords: | vehicle dynamics tire model magic formula side slip characteristic |
