ANSYS钢铁零件淬火热力学耦合有限元分析

摘要本文以钢铁零件为研究对象，利用ANSYS软件对钢件零件淬火过程进行热应力学耦合分析，模拟过程进行建模、网格剖分、加载及求解。分别改变不同淬火时间、淬火温度和淬火冷却介质的工艺参数，研究它们的温度场，应力场的分布，然后进行分析和对比。模拟结果表明淬火介质和淬火温度对淬火过程有显著影响。钢件淬火温度越高，零件心部的等效应力越高，钢件水淬火冷却内应力比油淬火冷却大，油淬火冷却介质的热稳定性和冷却均匀性比水好。对于现实工业生产淬火液的选取及淬火工艺的优化有重要的指导意义。68218

Title Finite element analysis about the thermodynamic coupling of steel parts in quenching process

Abstract

This paper takes a steel parts as the research object, thermal mechanical coupled analysis of quenching process of steel parts by using ANSYS software, the simulation process modeling, mesh, loading and solution. Process parameters of different quenching time, quenching temperature and cooling medium were changed to study their, temperature field, stress field, then analyzes and compares. The simulation results show that the quenching medium, quenching temperature has significant effect on the quenching process. The higher the quenching temperature of steel, the equivalent parts of stress is high, the steel water quenching stress than oil quenching, oil quenching cooling medium heat stability and cooling uniformity better than water. There is an important guiding significance for the selection and optimization of quenching process of actual production of the quenching liquid.
