| 摘 要： | 针对平面复杂机构位置分析，提出基于三角矢量回路的几何矢量法．从几何矢量的解法入手，提出了三角矢量回路的概念．根据是否可以解出三角矢量回路的情况，将机构位置分析方程分为两类，并分别给出相应解法，从而得出位置解．最后以四环基本运动链为例，说明了三角矢量回路的用法．

| Abstract: | Geometric vector method based on triangular vector loop is proposed for position analysis of planar complex mechanisms. The conception of triangular vector loop is proposed in view of solution with geometric vector, According to the situation whether the triangular vector loop can be worked out or not, the equations for position analysis are sorted into two types. The respective solution of each type is provided to obtain the roots of equations for position analysis. 4-loop BKC is used as an example to show how to use the triangular vector loop method. |
