提出弯管过程样条有限条分析方法 ,建立基于更新拉格朗日方法(U .L .法 )的弹塑性大变形样条有限条法的理论模型。采用该方法分析柔性制管过程变形带材的位移场、应变场和应力场。并应用可视化技术有效、直观、快速地显示模拟结果 ,对实际生产具有重要意义。

This paper presents the spline finite strip analysis method of cold-rolled forming section steel process, A theoretical model of elastic-plastic large deformation spline finite strip based on the updated Lagrange method has been established. By this method, the displacement fields, the stress fields and the strain fields of the deformed strip during flexible forming process are obtained. To display the results effectively and quickly, visualization technology has been applied. It is useful to the practical production.
