温度场的计算对淬火过程中热应力和热应变的分析有较大影响，对淬火后试件的残余应力和微观结构分析也有较大影响。本文以45钢圆柱试件为研究对象，采用文献［2］所得到的非线性表面换热系数，将Norsette法用于有限单元分析中，计算了淬火过程中的非线性温度场，有效地避免了在小时间步长下数值解出现震荡的问题。有限单元法数值解与实验结果吻合较好。
The calculation of temperature field has a great influence on the analysis of thermal stress and thermal strain during quenching, and also has a great influence on the residual stress and microstructure analysis of the specimen after quenching. Based on the nonlinear surface heat transfer coefficient obtained in reference [2], the Norsette method is used in the finite element analysis to calculate the nonlinear temperature field in the quenching process, effectively avoiding In the small steps under the numerical solution to the problem of concussion. Finite element method numerical solution and experimental results agree well.
