Modeling and simulation of a solar array deployment mechanism

With the focus on solar array deployment and latch-up technology for satellite, a solar array deployment mechanism is designed for satellite. This paper introduces its composition and analyses its mechanism. Numerical simulation results given by ADAMS and ANSYS demonstrate that the function and performance of the mechanism is rational. According to the simulation results, deployment time and fundamental frequency of solar array are obtained, and driving torque and latch-up force change trend with time of the mechanism are analyzed. The modeling and simulation methods purposed in this paper can be referenced for further study in designing and manufacturing other solar array deployment mechanisms.
