一类组合机构在极限位置作直到三阶停歇的设计原理

Designing principle of a kind of combined mechanism doing unto three orders intermission at limit positions

从复合函数的一阶导数等于零 ,导致其二、三阶导数在对应点上为零的数学特征中 ,提出了一类组合机构在极限位置作高阶停歇的设计原理。介绍了

From the mathematic character of an one ordered derivative of a compound function equals to zero which leads to the two and three ordered derivatives equal to zero on its corresponding points, the designing principle of a kind of combined mechanism doing high ordered intermission at limit positions was put forward. Four types of combined mechanisms possessing practical values and its designing method have been introduced.
