|
摘要
本文应用MARC有限元软件并采用三维热力耦合的弹塑性有限元法,对Y型三辊两道热轧不锈钢/碳钢双金属复合无缝钢管过程进行了有限元分析,得到了双金属复合无缝钢管界面处的接合强度,绘制了管坯热轧过程中的轴向应力、径向应力和环向应力,并对成型钢管的壁厚分布进行了分析。研究成果可以为工艺参数的设计提供参考。
The numerical simulation of the Y shape three roll two hot-rolling stainless steel / carbon steel double metal composite seamless steel tube process was conducted through the finite element analysis of the three-dimensional thermo-mechanical coupled elastic-plastic by applying the MSC. MARC software. Based on the numerical simulation,the interface bonding strength of double metal composite seamless steel tube were obtained by the finite element analysis,and the distribution of the axial stress,radial stress and circle stress were got in hot-rolling processing. Wall thickness distribution of the double metal composite seamless steel tube after forming was analyzed according to the stress distribution. The results of the research could be applied to the design of the cross-rolling forming process.
