As a complex sealed rotor system, the theoretical analysis and research of the system are carried out, and the related virtual prototype simulation work is done by using computer, and the experimental research is carried out. 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 the research of the sealed rotor system considering the gear meshing characteristics, the internal excitation is mainly considered, while the external excitation is ignored, such as the influence of the dynamic characteristics of the motor on the system. The dynamic characteristics of the motor can be taken into account to study the dynamic response of the system.
(2) In theory and simulation analysis, only four kinds of fixed speed rotor displacement dynamic response are studied, and then the dynamic response of the system under acceleration or deceleration can be studied.
