摘要
根据柔性单元的应用特点及高精度星敏感器遮光罩组件的构型特点,选用叶簧结构作为遮光罩柔性支撑结构的主体形式.通过分析支撑结构长度、宽度和厚度尺寸对弯曲刚度的影响,确定主要变量并展开优化设计.通过仿真验证设计结果在刚度和强度上均满足要求,法兰结构在遮光罩采用柔性支撑设计条件下产生的形变是刚性支撑设计的2. 14%.结果表明遮光罩柔性支撑结构设计合理有效,满足空间应用要求,可作为高精度星敏感器热稳定性设计优化的重要方法.
Based on the application characteristics of flexible unit and the structural characteristics of the baffle components of the high-accuracy star sensor,leaf spring structure is selected as the body of flexible supporting structure for the baffle.The main effects on bending rigidity are analyzed,which are made by length,width and thickness size parameters of the supporting structure.And the main variables are identified and the optimization design is carried out.The simulation analysis verifies that the design result meets the requirement on stiffness and strength,and the deformation of the flange structure with flexible supporting design is 2.14%of that with rigid design.The result shows that the design of flexible supporting structure for the baffle is reasonable and valid.It can satisfy the spatial application demand,and be used as an important method for the design optimization of thermal stability of the high-accuracy star sensor.
