Abstract
In order to study the handing stability of vehicles with five-link dependent rear suspension, a linear three-degrees-of-freedom handling model of the vehicle including rear axle compliance steering was established. The influences of the rear axle compliance steering on the vehicle under-steering characteristics were analyzed by the frequency domain method. The results show that the longitudinal location of the upper links intersection point and the bush stiffness of the upper links influence the vehicle under-steering characteristics. When the intersection point is located 1.65 m from the rear axle and the bush bending stiffness is 1.5 kN·m/rad, the vehicle under-steering performance is optimal. The simulation results of the theoretical model agree well with the experimental ones.
