摘要: 进行了某数控蒙皮横拉机的机构分析,开发了机构运动反解软件.并在UG软件中进行了机构的运动建模与计算机仿真.运动反解与计算机仿真的相互验证,确定运动反解软件的准确性.实现了拉形过程有限元模拟与拉形机作动筒伸缩控制的结合,为该设备的精确控制及效能发挥提供了技术基础.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.
