Static Analysis and Topology Optimization of Satellites Deployment Mechanism Hinges

In order to meet the needs of increasingly complex space missions, the size of the satellite body, large-area flexible solar arrays, large antennas, and other satellite outer large components of ground remote sensing , deep space probes and other satellite outer large components have been significantly increased compared with the past [1] – [4] . Due to the space constraints of the rocket, The large mechanism outside the cabin is installed in the fairing in a retracted attitude through the unfolding mechanism in the launch state. After the spacecraft enters the orbit, the large parts outside the cabin are deployed to the working state by the power source of the deployment mechanism [5] .
