摘要
采用ANSYS软件,对圆柱形试样的淬火过程进行有限元模拟,并将模拟结果与实际测得的冷却曲线进行对比。对比分析显示二者吻合,证明利用ANSYS进行淬火过程温度场模拟是可信的。对45号钢车轮件的水冷淬火、水油双液淬火过程的三维温度场进行模拟。模拟分析发现,45号钢车轮淬件尺寸较大,自身冷却速率较慢。采用水油双液淬火,由水淬转为油淬时,马氏体的转变受到较大影响,有可能导致淬不足的现象。
In this paper, ANSYS software is employed to simulate the quenching process of a cylindrical sample by finite element analysis. The simulation results are compared with the cooling curve recorded by experiment. It is found that the simulation results agree well with the experimental ones, suggesting that the modeling of heat transfer in quenching process by ANSYS is reliable. The threedimensional temperature fields of a steel （S45C） wheel are calculated under different conditions, water quenching and water-oil quenching process. Simulation analysis shows that for the steel （S45C） wheel, the cooling rate is relatively small because of its big size. When water-oil quenching is used, the transform of martensite is greatly affected when changing from water cooling to oil cooling, probably resulting in underquenching.
