摘要: 采用弹塑性大变形样条有限条方法分析了辊式成形过程,建立了辊式成形过程样条有限条分析的数学模型,编制了C语言程序。采用该方法分析计算了两成形机架变形区变形后的形状及纵向、横向应力应变分布。与试验结果进行了比较,表明样条有限条法的计算结果是准确可靠的,从而为成形辊的计算机辅助设计及制造奠定了基础。

Abstract: Roll forming processes are analyzed, by using the large deflection elastic-plastic spling-finite strip method. By means of this method, the deforming shape of sheet metal interstand of rollers and the distribution of transvertsal and longitudinal strain and stress are calculated. Compaired with the experimental results, theoretioal results are correct and reliable. It lays the foundation for the CAD/CAM of forming rollers.

Key words: Elastic-plastic, Finite strip, Roll forming, Spline function
