Abstract:A new shear viscous damper for on-line eliminate of rotor rubbing vibration was proposed aiming at fitting for the poor working conditions and compact structure cases. The vibration suppression effect of the damper for a single disc rotor system supporting on the sliding film bearings was theoretically study by the finite element method. Its mathematical model was a vibration system including nonlinear rub force, nonlinear oil film force and the applied shear damping force, numerical calculation for it by the fourth-order Runge-Kutta method, and the vibration response for rubbing rotor after applied the damper was analyzed comparatively. Theoretical results obtained from the numerical simulations of the model are verified by the experimental study. Simulation and experiment results show that the damper can effectively eliminate the complexity rub rotor system orbit and two or other high-frequency vibration peak,.
