  • The perfect combination of virtual simulation technology and orthogonal experimental design methods provides a new idea for the automotive product development. The research of steady state circular performance of automobile can follow the following steps. A virtual prototype model of a car was established in multi-body dynamics simulation software automatic dynamic analysis of mechanical systems(ADAMS); The testing program was reasonably designed using orthogonal experimental design methods; Some simulation tests were carried out in ADAMS following the designed testing program; The optimal testing program and the influence degree of every factor were elicited after the test data being calculated and analyzed. The results show that the four factors which have considerable influence to the steady state circular performance of automobile are the location of mass center in lengthwise, the cornering stiffness of front and rear tires, the height of mass center, the stiffness of front spiral spring, according to the order of influence degree.
