Research on the disturbance generated by a solar array drive assembly driving a flexible system
The present work is aimed at presenting the disturbance generated by a solar array drive assembly (SADA) driving a flexible system. Firstly, the vibration equation of SADA is obtained by simplifying and linearizing the electromagnetic torque. Secondly, the disturbance model of SADA driving a discrete flexible system is achieved based on the vibration equation established. Taking a two-dof flexible system as the study object, this disturbance model is simulated and analyzed. Lastly, a continuous flexible system, which is designed to simulate the solar array, is used to illustrate the simulation method of the disturbance emitted by SADA driving a continuous flexible system. All the achievements obtained from this project will provide a theoretical basis for the prediction of the disturbance emitted by the SADA driving solar array on the orbit.
