| Abstract: | This paper focuses on the dynamics of large spacepower stations during on orbit deployment and assembly.Considering a large power station as a rigid flexiblemulti body system, the rigid body modeling is performedby using natural coordinate formulation (NCF) for the rigid members, and theflexible truss structures are described based on the absolute node coordinateformulation (ANCF). The authors have compiled a set of dynamics simulationsoftware to achieve the accurate simulation of the on orbitdeployment and assembly dynamics of large space power stations. The simulationresults show that using the cycloid function as the governing function isadvantageous to improve the stability of the multi stagedeployment process. In the structure assembly process, reducing the assemblyspeed as well as increasing the damping coefficient and stiffness arebeneficial to improve the structural stability. This paper integrates a set ofdynamic simulation platform construction methods for large space powerstations, providing theoretical basis and method guidance for large space powerstation on orbit deployment and assembly dynamicsprediction. |
