Some research is done on the intermittent-motion linkage with slight difference in length between the links. To analyze and evaluate the usability of this intermittent-motion linkage in practical engineering

some analyses of the special linkage

such as the law of motion

the mechanical advantage

the transmission and dynamic characteristic

are done. At the same time

the virtual prototype of this special mechanism is also taken into analysis on the Adams system by making use of its powerful functions on kinematics as well as dynamic simulations. The results of these studies show that this special intermitted-motion linkage has a good usage property. This research shows some theoretic foundations for the practical usage of the intermittent-motion linkage.
