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间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 The roll forming process was analyzed by the finite element method of elastic-plastic large deformation spline. The mathematical model of spline finite strip analysis was established and the C language program was compiled. Using this method, the deformed shape and longitudinal and transverse stress-strain distribution of deformation zone between two forming racks are analyzed and calculated. Compared with the experimental results, the results of the spline finite strip method are accurate and reliable, which laid the foundation for the computer-aided design and manufacture of the forming roll
