对称结构静力分析

本文从力学对称原理的基本概念出发,对静力学部分,提出将传统的单一坐标系变换为一套相互对称的辅助坐标系,从而使得进行对称结构静力分析所用公式简单明了。据此,在计算机上求解对称结构具有三个优点:①节约机器存贮空间;②减少数据准备工作量;③节省机时。

The Static Analysis of Symmetrical Structures

Based on the essential concepts of the symmetry principle in mechanics, this paper discusses some problems in statics and suggests a method by which a traditional unitary coordinate system is changed into a set of auxiliary ones, which are symmetrical to each other. This method makes the formulations simple and clear and easy to use when static symmetrical structures are solved with the symmetry principle. In comparison with common methods, the use of this method to solve symmetrical structures with an electronic computer has the following advantages: less initial data preparation, smaller storage requirment, and less CPU time.
