本文介绍了一种利用现有的具有前后处理功能的有限元软件包（如SuperSAP91）通过模态分析间接计算复杂结构天线转动惯量的方法，并给出了一个工程实例。此法对处于图纸设计阶段的复杂结构天线转动惯量的计算有足够精度，对天线驱动电机的选择和伺服系统的设计会有所帮助。
This paper introduces a method of indirectly calculating the moment of inertia of complex structure antenna by modal analysis using the existing finite element software package (such as SuperSAP91) with pre-processing and post-processing functions, and presents an example of the project. This method has enough accuracy to calculate the moment of inertia of the complex structure antenna in the stage of drawing design and will be helpful for the selection of antenna driving motor and the design of servo system.
