Based on the establishment of resilient wheel vehicles-track coupling model, the movement differential equation systemwas deduced; Dynamic resilient wheel vehicle model was established by Simpack, and the ratio of the radial stiffness and lateralstiffness of the elastic element had been optimized based on the vehicle stability and curving performance. With optimized stiffness, theadaptability of resilient wheel and rigid wheel on different track line had been researched. The results show that the ratio of the radialstiffness and lateral stiffness of the elastic element in the range of 0.75 to 1.5 can achieve an ideal dynamic performance; Track conditionsgets worse, the effect of elastic wheel gets more obvious.
