Study on nonlinear dynamics of a rotor-bearing system with coupled faults of crack and rub-impact

Abstract

A nonlinear dynamic model is established to analyze the complicated dynamic behaviors of a rotor-bearing system with coupled faults in this paper, where the time-varying crack stiffness, rub-impact force and nonlinear oil-film force are taken into consideration. The numerical simulation focuses on the effects of crack depth on the onset of instability and… (More)
