| Abstract: | Stability and Hopf bifurcation of vehicle hunting are analyzed by applying the center manifold normal forms method, and the amplitude coefficients of bifurcation solution and its criterion for stability are obtained. It is shown by results that the amplitude coefficients of first bifurcation solution are mainly determined by wheel track nonlinear geometry relationship, linear creep forces, linear suspension parameters. |
