浅谈替换思想及无穷远虚铰在几何组成分析中的应用

A Brief Discussion on the Application of Substitution Thinking and Infinity Imaginary Hinge to Geometric Composition Analysis

在对平面杆系做组成分析时,采用等效替换思想和灵活运用虚铰在无穷远的各种情况下的结论,有助于将结构复杂的平面杆系转化为较为简单的平面杆系进行几何组成分析。本文主要进行总结和概括,使等效替代思想和虚铰在无穷远情况更系统化。

When making composition analysis of plane link sys-tem, to adopt equivalent substitution thinking and flexibly use the conclusions of imaginary hinge under various situations of infini-ty, is conducive to transforming complicated plane link systems to relatively simple plane link systems, so as to carry out geometric composition analysis. This paper mainly carried out the conclu-sion and summarization, in order to make equivalent substitu-tional thinking and imaginary hinge under the situations of infini-ty more systematic.
