| Abstract: | The complex nonlinear dynamics of a rotor-bearing system with crack and rub-impact was studied.Taking into account of real characteristics of the nonlinear rotor-bearing system,the rolling element bearing,rotor-bearing system with crack and rub-impact along with its nonlinear dynamics model,the bifurcation diagram,poincare mapping and frequency spectrum diagram of the system under certain parameters were obtained by numerically analysis with Runge-kutta method,which indicated the dynamics of the system intuitively.And the fault characteristics were also studied.The results brought in theoretical references for the fault diagnosis of rotor-bearing system with crack and rub-impact metioned above. |
