By the kinetics standpoint it had built up a position expression type of the link mechanism, in addition, explained clearly the automatic computation its data of movement analysis and the result process in graph, finally, there alization method about the link mechanism movement simulation had been introduced. KEY WORDS: link mechanism; math CAD; slipper block; movement analysis; simulation. I. INTRODUCTION Over the past few decades, engineering schools have placed a high priority on incorporating computer technology into the engineering curriculum and this has been no incidental achievement Specially, this article take swings feeds in the analysis of mechanism as an example, introduced using the Math CAD software to carry on the movement analysis and the simulation method to analyze the swing-type feeding mechanism, and explain the theories analytical method of these type of engineering problem thereby. II. MOVEMENT ANALYSIS OF LINK MECHANISM This swing-type feeding in the mechanism, the anti clock wise rate of angular motion of original moving parts is:ω1= 40rad/s ，and its structure with various components size as shown in Fig.1.In Fig.1 above the swing-type feeding in the mechanisms consist of the crank original moving parts 1 i.e. _grade pole group and the _ grade pole group.
