摘要

介绍了一种对反射镜轻量化结构进行优化设计的方法。利用ANSYS软件对采用扇形开口孔轻量化的某遥感器主反射镜建立参数化结构模型

将对反射镜力学性能影响较大的某些结构参数如镜体厚度、扇形孔的位置、尺寸等指定为优化设计变量

根据反射镜的加工和装配工艺合理地确定这些结构设计变量的可行域

运用ANSYS优化设计模块提供的零阶优化方法对镜体结构进行了优化设计。力学分析表明

经过优化后的反射镜结构相比于原设计方案轻量化程度更高

静力学性能更好。

Abstract

A parametric structure model has been established using FEA software ANSYS for an aspherical primary reflector with lightening sector holes. With some structural parameters having significant effect on mechanical properties of reflector

such as thickness of reflector

and location and size of sector hole

used as design variables

and feasible domains established in accordance with reflector machining and assembly processes for these design variables

an optimal design is done for the structure of a reflector using the zero-order optimization method provided in the Design Opt module of ANSYS. Mechanic analyses show that the optimized structure of the reflector is much lighter and stronger than the original design.
