摘要

空间望远镜的镜筒桁架结构优化以构件总质量等于常数为约束条件

以横向摆振频率最高为优化目标。优化分两步进行:首先以瑞雷方法和简化模型为基础

在较大范围内对可能的模型进行筛选

得出桁架分层数和每层斜杆数的最优解;然后用ANSYS软件对桁架杆、梁截面参数进行优化

得到比较满意的结果。此方法也适用对其他类似的筒状桁架的优化。

Abstract

In order to make the first order natural frequency of a Space Solar Telescope the highest under the restriction of a constant total mass

the optimization of the tube truss is accomplished in two steps: 1) the tier number of the truss and the web-member number in each tier are established using a series of simplified structural models; 2)the cross sections of all the members of the truss are optimized using ANSYS software.
