摘　　要：在热处理工艺中淬火是工件性能最不容易控制的部分。为了确定工件淬火后的组织转变及残余应力,必须掌握淬火过程中的工件内部温度随时间变化的分布规律。阐述淬火温度场的计算方法,应用Visual C++开发出一个专用的重轨淬火有限元分析的仿真软件。该仿真界面友好交互,只需要在人机界面上输入相应的参数,包括重轨淬火的加热、保温、冷却时间等,就会后台调用有限元软件对重轨淬火过程进行有限元数值模拟,获得其温度场分布,通过对比分析得到最佳加热时间,并制定出较优的重轨淬火工艺。The quenching was not easy to control the performance of the work piece in the heat treatment process.In order to determine the organizational transformation and residual stress after quenching,it must grasp the internal temperature distribution with time-varying of the work piece in the quenching process.This paper elaborates the calculation method of quenching temperature field,and the simulation software of a dedicated rail quenching finite element analysis is developed by Visual C++.The simulation interface is friendly interaction,only needs to input the corresponding parameters in the man-machine interface,such as temperature-dependent thermal properties and operation conditions,then it will call the finite element software to carry out the finite element numerical simulation of quenching process in the background,then the distribution of temperature field is obtained.Through the comparative analysis of the optimal heating time,the optimal rail quenching process is developed.
