摘　　要：固面可展开天线反射体由面板、背架、中心体、支撑杆、托盘和驱动机构组成。展收时驱动机构驱动托盘带动背架运动实现反射体的展开和收藏。通过有限元模拟分析了反射体的结构变形精度和不同工况下背架上的受力情况,通过Adams仿真计算了收藏过程中驱动机构的出力变化。可知,该设计满足设计要求,可在保证反射面精度的条件下大大提高天线的机动性。The deployable rigid reflector for the Antenna is composed of the panel,back frame,center body,support rod,pallet and driving mechanism.To make the reflector folded and deployed,the driving mechanism drives the pallet move and the back frame moves.The structure deformation accuracy of the reflector and the stress of the back frame under different working conditions are analyzed by the finite element analysis method.The output force of the driving mechanism is calculated by the Adams.The design satisfies the requirements and can greatly improve the maneuverability of the antenna while ensuring the accuracy of the reflector surface.
