【Abstract】 By applying the principles of coordinate transfer and introducing Euler parameters, the constraint equations of key points are formulated, and the law that parameters such as caster, camber, toe in and wheel base vary with the wheel moving up and down is deduced. A new method of analyzing the motion of wishbone independent suspension is put forward. To different types of automobile, the kinematics simulation was implemented by using the code developed .The simulation results agree with the experimental data quite well.更多还原
