  • The traditional folding solar array with large size and big mass, using single deployment and locking mechanism, can cause flutter during the spacecraft attitude adjustment or orbital transfer, and hence a fan-shaped solar array with repeated fold-unfold and lock-unlock mechanism scheme was designed. A virtual prototype model is established based on ProE/Adams co-simulation, and the motion parameter changing rule of the pivot panel at different motor rotational speeds is obtained. The deployment function verification test is carried out using the prototype. By comparing the simulation result with the test data, it can be known that the mechanism can be fully deployed and locked in time when the motor speed is changed in prescriptive range, and can be deployed and locked repeatedly. The simulation result is highly consistent with the test data, which shows that the design can meet the requirements.
