| Abstract: | A misalignment-rubbing coupling faults' dynamic model of rotor-ball bearings system was established in this paper.In the misalignment force model of the coupling,the reasons of inducing misalignment force were analyzed;in the model of rotor,the coupling faults that were induced by misalignment,unbalance and rotor-stator rubbing were considered.The numerical integral method was used to obtain nonlinear dynamic responses of rotor system,and the model of misalignment force and the model of ball bearings were v... |
