Abstract

In order to analyze the startup transient response of a flywheel system, its shaft system is studied in this paper: The transient oil forces of a squeeze film damper (SFD) in fixed frame are firstly derived. By putting the Wilson- formulation integration method which having damp of algorithm into the motion equations of a rigid disc’s barycenter, the transient transfer matrix of a station made of a disc and a shaft is also built which can improve algorithm stability. The transient-state response equations of the flywheel shaft system are built and solved by putting Taylor series and numerical iteration into the transfer matrix method, and the startup transient-state response curves of rotor with different constant angular acceleration are finally obtained. The calculation results show that the theoretical method introduced in this paper can be used to analyze the performance of quick charge of a flywheel shaft system.
