This paper develops a structure-attitude coupled dynamic model for reconfigurable multi-flexible-body spacecraft. A graph theory-based algorithm is proposed to update the dynamic model’s parameters during assembly, including mass, stiffness, and inertia matrices. To validate the effectiveness of the proposed method, a simulation model was established for the on-orbit assembly task of a Modular Multi-Rotary Joints Solar Power Station. Results show the significant impact of structural flexibility on attitude dynamics and reveal the sensitivity of spacecraft attitude stability to configuration changes, as well as orbital altitude under the influence of environmental torques.
