摘要
举例分析了组成无穷远铰的平行链杆为异侧或同侧情况下的平面体系几何组成,认为目前平面体系存在无穷远铰时的几何组成分析规则有待商榷,并通过分析平面体系发生微小位移后的几何特征,对该类问题的分析方法进行了探讨,完善了"铰接三角形规律"。
The geometric composition of a plane system with virtual hinged infinity which is formed by the same side or the opposite sides parallel chains is analyzed through examples. The problem on geometric composition analysis in plane system with virtual hinged joint infinity is pointed out. And then by analyzing the geometric characteristics of the plane system after a slight displacement,the analysis methods of the problem are discussed. And the method of "articulation triangle" is perfected.
