摘　　要：该文的研究对象是一种特殊的Bricard6R机构——普通面对称机构.在6根连杆等长,且铰链连接、偏置为零的情况下,分析了连杆的闭环方程,得到了输入输出角之间的关系.同时通过分析,得出该机构的彼此相间隔的三点构成的平面相互平行.然后,通过Adams仿真,验证了之前理论分析的正确性.This paper deals with one of the six distinct types of Bricard 6R linkages, the general plane-symmetric case. The closure equations of the linkages are analyzed and the relationship between the input and output angle is achieved, on the premise of six links of the same length and the six revolute joints of zero offset. And by analysis, it is found that the two planes constituted of three interval points are parallel to each other. Then, the correctness of the academic analysis is verified with Adams simulation.
