Nonlinear Responses of a Rotor-Bearing-Seal System with Pedestal Looseness

Nonlinear Responses of a Rotor-Bearing-Seal System with Pedestal Looseness

In this paper, a pedestal looseness fault model of a rotor-bearing-seal system is established. Under two working conditions of the same direction eccentricity (Working Condition 1) and reverse eccentricity (Working Condition 2), rotor orbits, vibration waveforms, spectrum cascade, and Poincaré maps...
