摘　　要：高阶停歇机构的设计理论是机构设计理论的重要分支之一。数学分析表明，若复合函数中两个基本函数在同一时刻的1阶导数同时为0，则复合函数的1～3阶导数在对应时刻为0。设两个基本函数满足了上述条件，则输出构件在对应位置作直到3阶的停歇。此数学原理开创了一种新的基于两个基本机构组合的位移函数同时为0的从动件作直到3阶停歇机构设计的非迭代方法。该方法比迭代方法简单，不存在理论误差。为此，研究了摆杆在极限位置作直到3阶停歇的串联导杆机构的设计与传动特征。The designing theory of high ordered intermittent mechanism is one of the important branches in the designing theory of mechanism. The mathematical analysis showed that if the first ordered derivatives of two basic functions of the compound function were zero at the same time then the derivatives from first to third or- der of the compound function would be zero at the corresponding moments. If assuming the two basic functions were satisfying with the above conditions then the outputting component parts would do up to the third ordered intermittent rest in the corresponding position. This mathematical principle opened up a kind of new non-iteration method for the design of mechanism with its follower doing up to the third ordered intermittent rest based on the displacement functions of the combination of two basic mechanisms to be zeros at the same time. This method is simple than the method of iteration and there exists no theoretic errors. Therefore, the design and transmission characteristics of the series leader mechanism with its follower doing up to third ordered intermittent rest at the limiting position were studied.
