As a complex sealed rotor system, the theoretical analysis and research of the system are carried out in this paper. In the process of studying the dynamic characteristics of the system, it is found that the following problems are worthy of further research and improvement.
(1) In this paper, the influence of internal excitation on the dynamic characteristics of the system is mainly considered in the study of the sealed rotor system considering the gear meshing characteristics, while the external excitation, such as the dynamic characteristics of the motor, is ignored. The dynamic characteristics of the motor can be taken into account to study the dynamic response of the system.
(2) In the theoretical and simulation analysis, this paper only studies the dynamic response of rotor displacement at four fixed speeds, and then studies the dynamic response of the system under acceleration or deceleration.
