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。
Roll forming procuses 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 re- sults are correct antd reliable.It lays the foundation for the CAD/CAM of forming rollers.
