摘　　要：平面体系的机动分析是结构力学课程教学中的重点和难点之一,是学习结构力学后续内容的基础和前提。针对机动分析时学生遇到的实际问题,经过对大量习题的分析、归纳和总结,提出平面体系"2+2+3+4"机动分析模式,使平面体系机动分析过程可以按照一定的模式和步骤进行,让看似无从下手的分析变得有章可循。针对三种不同机动分析方法,分别辅以例题对分析步骤进行详细说明,为结构力学平面体系机动分析教学提供新的模式和参考。Geometric components analysis of plane system is one of the most important and difficult parts in the course of structural mechanics, and it is the basis and prerequisite for the study of the following content of structural mechanics. In view of the practical problems encountered by students in geometric components analysis, ＂2 ＋ 2 ＋ 3 ＋ 4＂ model for geometric components analysis was put forward through analysis, induction and summary of a large number of problem sets. The model makes the process of geometric components analysis of plane system be carried out in accordance with certain model and steps, and makes the seemingly impossible analysis become rule-based. According to the three different methods supplemented in detail with analysis steps. It of plane system in structural mechanics. for geometric components analysis, provides new model and reference for examples were respectively geometric components analysis
