摘　　要：对大型外卷边槽钢产品冷弯中梁的辊弯成型过程进行了三维弹塑性有限元模拟,详细的分析了成型过程当中的变形情况、应力分布情况、应变分布情况,并与现场情况进行了比较,趋势吻合较好,验证了模型的准确性,为成型相关产品的过程提供了理论基础。Three-dimensional elastoplastic finite element method is adopted to simulate the rolled forming process for cold-rolled center sills of large-scale channel section products with outer edge. The deformation, stress distribution and strain distribution in forming process were analyzed in detail and compared with site conditions and they agree well with each other and verified the accuracy of model which provides theoretical foundation for the forming process of relevant products.
