Two Dimensional Deployable Mechanism for Satellites

This study presents a kind of two dimensional deployable mechanism with two vertical axes. This mechanism could be folded and deploy in two dimension in space, which will greatly increase the effective area for solar panel or radiator on satellites. The conceptual design and frequency analysis of the mechanism are carried out. The compact hinges with high stiffness and lightweight drive mechanisms are applied in the mechanism for controllable deployment. The zero gravity environment simulation method and the test system are researched for testing the capability of the mechanism on ground accurately. The design of the zero gravity simulation system is presented with mechanical parts and controlling parts.
