Design on Large Space-Borne Sailboard Based on Flexible Multi-body Dynamics

In this article, it describes the method to perform the spacecraft solar array development process modeling by using the flexibility multi-body kinetics and Kane equation, it regards the windsurfing as the flexible body and performs the modal analysis, adopts the FEM and modal condensation technology to establish the discrete model, takes a domestic type of the spacecraft as the example, at the same time takes the flexibility of the 4 pies of windsurfing into consideration, uses the ADAMS software o perform the modeling and simulation to the development process of the windsurfing, and obtains the kinetics parameters such as the morphs and wide range of motions to provide certain evidences to the design of the spacecraft solar array.
