太阳翼二维展开阶段SADA不同控制状态仿真分析
Simulation Analysis During Two Dimensional Deployment of Solar Wing Under Different SADA Work Status
摘要
Abstract
The reverse rotation of SADA (solar array drive assembly ) appears during the deployment of side panels of two dimensional solar wing.The resistance moment equations of SADA under its power on/off status are established with electromechanical coupling method,and based on the recursive method the differential-algebraic equations of satellite dynamics during the deployment of side panels are presented,and the effects of side panels deployment for solar wings and satellite safety under SADA power on/off status are analysed.The results indicate that the deployment of side panels will make the SADA rotate with the large angular velocities and endan-ger the safety of SADA electrics circuit,the suggestions are proposed that the proper SADA ON/OFF strategy should be applied and the measures of decreasing the angular velocity of side panel deployment should be applied combined with the circuit design of SADA.关键词
