Nonlinear vibration and stability analysis of a dual-disk rotor-bearing system under multiple frequency excitations

This paper aims to investigate the nonlinear vibration characteristics and stability of a dual-disk rotor-bearing system under multi-frequency excitations. A 4-degree-of-freedom dynamic model is established using the assumed mode method, considering the bearing’s cubic nonlinearity. The system is so...
