The dynamical behavior of a strong non-linear system with clearance containing non-smooth factors and friction was investigated. Dankowicz kinetic friction model was introduced into the system, the judgment condition for the oscillator force-bearing was deduced. Combined with the numerical simulation, the friction induced vibration and the effects of other key parameters on the dynamic characteristics of the system were explored. The results showed that under different parameters, there are complex and various forms of friction-induced vibration in the system, such as, stable periodic friction vibration, quasi-periodic friction sticky vibration, quasi-periodic instantaneous friction induced vibration, flutter impact, friction induced sticky impact vibration, friction induced sticky chaotic vibration, etc.
