| Abstract: | The dynamic model of vibro-impact system with clearance and elastic constraint is simulated by numerical method of the step-varying Runge-Kutta of four order,and the system's global bifurcation diagrams are elicited under different parameters,which shows the effect of different parameters on dynamic behavior,and the process of dynamic system tending to chaos.All these conclusions can provide theory reference for the optimizing of system parameters and the control of this system. |
