This article summarizes the research status of nonlinear rotor-bearing dynamics system in china and abroad, discusses several major problems of nonlinear rotor-bearing dynamics system and refers to a large number of references. The review includes the following three aspects: modeling for the nonlinear oil film force of rotor-bearing system; general analysis methods of nonlinear rotor-bearing system; and numerical analysis methods of nonlinear rotor-bearing system. Furthermore, the problems in current research are pointed out, and the development tendencies are also described: further research on the model of nonlinear oil film force; The dimension reduction methods of high-dimensional nonlinear rotor-bearing dynamics system and optimal design of multi-degree of freedom coupled system; nonlinear parameter identification, modeling and reconstruction methods of rotating machinery; optimal design of nonlinear dynamics for large rotating machinery; Research on the sensitivity analysis of nonlinear vibration and the stability, nonlinear stability margin and nonlinear stability criteria of rotor-bearing-basis coupled system; analysis and research on nonlinear dynamics of rotor-bearing-seal system.
