【摘要】 次镜组件是空间光学遥感器中至关重要的一个组件,次镜组件中的柔性铰链又是次镜组件的一个重要组成部分。本文介绍了柔性铰链的设计原则,应用OptiStruct结构优化设计平台对柔性铰链进行了优化设计,并对优化结果与经验结构进行了对比验证,优化后的柔性铰链使次镜组件的一阶频率,镜面面形得到明显改善,同时柔性铰链的轻量化率高于原始设计方案。更多还原

【Abstract】 The secondary mirror unit is one of the most important part in the spaceborne remote sensor,and the flexure hinge is a crucial component of the secondary mirror unit.In this paper,the design criterion of the flexure hinge is introduced,with the help of OptiStruct,topology optimization is performed in the procedure of flexure hinge design.By contrast with the conventional flexure hinge,the result shows that the first mode of the secondary mirror unit,the surface-shape and the lightweight ratio are better than the conventional structure.更多还原
