Abstract

This paper focuses on the dynamics of large space power stations during on-orbit deployment and assembly. Considering a large power station as a rigid-flexible multi-body system, the rigid body modeling is performed by using natural coordinate formulation (NCF) for the rigid members, and the flexible truss structures are described based on the absolute node coordinate formulation (ANCF). The authors have compiled a set of dynamics simulation software to achieve the accurate simulation of the on-orbit deployment and assembly dynamics of large space power stations. The simulation results show that using the cycloid function as the governing function is advantageous to improve the stability of the multi-stage deployment process. In the structure assembly process, reducing the assembly speed as well as increasing the damping coefficient and stiffness are beneficial to improve the structural stability. This paper integrates a set of dynamic simulation platform construction methods for large space power stations, providing theoretical basis and method guidance for large space power station on-orbit deployment and assembly dynamics prediction.
