Stochastic Responses of a Vibro-Impact System with Additive and Multiplicative Colored Noise Excitations
International journal of dynamics and control(2014)
摘要
By the aid of nonsmooth transformation, the stochastic averaging method is extended to solve the stationary response of a vibro-impact system with additive and multiplicative colored noise excitations. The stationary responses are obtained by using the concepts of total phase and residual phase. A Duffing–Van der Pol vibro-impact system is given to illustrate the application of the method. And stochastic P-bifurcation is also investigated.
