Due to the extensive applicability in real life,the non-smooth system with random factors attracted much attention in past two decades.A lot of methods and techniques have been proposed to research these systems by scholars.In this paper,we will summarize some new research advance on the stochastic non-smooth systems.The existing results about the stochastic vibro-impact system,the stochastic friction system,and the stochastic hysteretic system are introduced respectively.Some conclusions and outlook are given at the end.
