    Abstract
  • In order to determine the effect of the sensitivity of steering system on the shimmy of front wheel under braking condition, wheel, front axle and leaf springs were considered as a whole, the changes of dimensional states of leaf spring and steering system were analyzed, a mathematic method of the shimmy angle of front wheel was proposed, and the sensitivity of steering system was evaluated with the shimmy angle resulted from the change of dimensional state of steering system. Computation result indicates that the maximum of the shimmy angle is 0.5° when braking force is 35 kN. Obviously, the sensitivity of vehicle steering system is lower, the evaluation result accords with its real state, so the method is feasible.
