摘　　要：采用ANSYS Workbench软件的热分析模块,结合材料在温度变化过程中热物性参数的变化,对外形复杂的45钢齿轮零件淬火过程温度场进行了数值模拟,取得了本零件温度随淬火时间的分布关系,模拟结果与实际过程一致。该方法优于传统的人工测量和经验判断方法,其模拟过程为分析计算淬火过程的热应力和残余应力提供了一定的理论基础。Combined with change of the thermal physical parameters of materials, the temperature field of 45 steel gears in quenching processes has been numerically simulated by using the thermal analysis module of ANSYS Workbench soft-ware. The relationship between temperature of gears parts and quenching time was achieved, and the simulation results were consistent with actual process. The methods is superior to the traditional manual measuring and experience judgment way. The simulation process provided the due theoretical basis for the calculation of parts thermal stress and residual stress in quenching process.
