摘要
A four-wheel-steering system under white noise excitations is reduced to a two-degree-of freedom quasi-non-integrable-Hamiltonian system at first, and then reduced to a one-dimensional Ito stochastic differential equation for the averaged Hamiltonian by using the stochastic averaging method. Thus, the stochastic Hopf bifurcation of the original system is determined approximately by examining the sample behaviors of the averaged Hamiltonian near the two boundaries, and conditions for stochastic Hopf bifurcation of the four-wheel-steering system are presented.
