Dynamical behaviors of a nonsmooth vibration system containing segmented damping, segmented spring and modified LuGre dynamic friction were investigated. The mechanical model and kinematic equation of the system were established. The movement transformation processes of the system were analyzed. The dynamical behaviors of the system, which converts among the modes of slipping, sticking, oscillation contact and chattering, were discussed by numerical simulations. The results show that the complex and diverse forms of the friction induced vibration like the friction induced stickingchattering vibration,the friction induced sticking vibration, etc.exist in the system with definite system parameters.
