摘要
运用"可能域"的概念建立模型空间,得到平面Ⅳ级杆组的所有可能构形。再根据排列组合论和运动链同构判定的邻接矩阵法证明,在全转动副的基础上,含R、P副平面Ⅲ级杆组可演化成其它23种不同的构形。
In this paper, the model space is built using the concept of ＂output domain＂, then all the possible configurations of gurth stage perches in flat pair are got. It is proved that the third stage perches can be evolved to 23 configurations with R,P planar pair based on the overall turning pair, according to the theory of permutation and combination, and the methord of adjacency matrix.
