以冷轧铅为模型 ,用MARC有限元软件对钢轨的轧制过程进行三维弹塑性模拟 ,并分析轧制状态下钢轨内部应力的分布以及轧后残余应力分布 ,为提高钢轨质量 ,适应国内高速铁路的建设奠定了理论基础。
Using cold rolled lead as a model, the three-dimensional elastic-plastic simulation of the rail rolling process was carried out with MARC finite element software. The distribution of internal stress and the residual stress distribution after rolling were analyzed. In order to improve the rail quality and adapt to the domestic high-speed The construction of the railway has laid a theoretical foundation.
