Abstract

Dynamic behavior of the vehicle shimmy system with consideration of steering linkage clearance was analyzed. Based on nonlinear dynamic theories, the movement pair clearance between the steering tie rod and tie rod arm was described with Hertz model, and 4 DOF dynamic model of vehicle shimmy system with consideration of steering linkage clearance was presented. The dynamic behavior of the vehicle shimmy system with clearance was analyzed with phase portrait, Poincaré map, and bifurcation diagram, which provided theoretical basis for attenuation of vehicle shimmy.
