Description

technical field [0001] The invention relates to the technical field of aerospace vehicles, in particular to a fast modeling method and system for the dynamics of a solar wing of a spacecraft. Background technique [0002] At present, most of the deployable solar wings mainly adopt the structural form of the interconnection of the composite material substrate and the hinge between the panels. After orbiting, it automatically unlocks and unfolds to provide power for the spacecraft to work in orbit, which is an indispensable part of every spacecraft. As a large flexible part of the spacecraft, the dynamic performance of the solar wing in the retracted state and the deployed state is very important, which directly affects the frequency shift design of the active segment of the secondary structure of the spacecraft, and the attitude control and load of the entire star after deployment in orbit. Therefore, It is necessary to carry out kinetic analysis on it. In the past, the dyn...
