摘 要：应用ANSYS软件建立了钢轨的有限元模型。通过对钢轨模型的有限元分析，得出了不同工况条件下的钢轨上应变场的变化趋势，得到了不同工况处的中性线上节点的数据，并应用数学方法找到了在钢轨中性线上对应变敏感的确切位置。这些数据为以后弹性体的粘贴以及钢轨传感器的设计奠定了基础。

Abstract: Finite element model of rail was built up by means of ANSYS. With the analysis of finite element model, the rail field trend was known and the strain data of node along rail neutral line was got by differently loading on the finite element model. The strain sensitization area on rail neutral line can be found accurately by mathematic method. These data is later the flexible body glued to stick to lay foundation, and it is important to design the electrocircuit in the future.
Key words: ANSYS; rail; strain; finite element analysis
