Abstract�� On the basis of analysis of the mechanism of a numerical controlled transverse stretching machine, the software of the mechanism motion analysis was developed by reverse solution method. And the model and motion simulation of this machine were built in UG software. The accuracy of the reverse solution software was verified by the comparison between the motion reverse solution and computer simulation. The combination of the FEM simulation of stretch forming process and the axes extension control of stretching machine was realized, which provides the technological basis of accurate control and efficient exertion for this machine.
Keywords�� skins   computerized simulation   stretch forming   motion reverse solution   equipment control
