摘　　要：通过Y型三辊二道次冷轧不锈钢/碳钢无缝管双金属复合材料成型过程模拟,得到了双金属复合无缝钢管界面处的结合强度,绘制了无缝钢管成型过程中的轴向应力、径向应力和环向应力,并且对成型钢管的管径与壁厚分布进行了说明。研究成果可为复合无缝钢管成型的工艺参数设计提供参考依据。A finite element analysis of the elastic-plastic by applying the MSC. MARC software was put for- ward, the numerical simulation of the Y shape three roll two cold-rolling stainless steel/carbon steel double met- al composite seamless steel tube process was conducted. Based on the numerical simulation, the interface bond- ing strength during the Y shape three roll two cold-rolling were obtained by the finite element analysis. The dis- tribution of the axial stress, circle stress and radial stress were drawn below the Y shape roiling mill along the circle. The mechanism of the tube cold-rolling process and the effect of the forming steel tube both the diameter and wall thickness accuracy were explained according to the stress distribution. The results of the research can be applied to the design of the technical parameters in the forming process.
