Motion analysis and simulation control of numerical controlled transverse stretching machine for aircraft skin

By analyzing the mechanism of a numerical controlled transverse stretching machine, the software of the mechanism motion analysis was developed by the reverse solution method. The motion model and computer simulation of this mechanism 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 finite element simulation of stretch forming process with the axes extension control of this machine was realized, which provides the technological basis of accurate control and efficient working for this machine.
