摘要/Abstract

摘要： 基于热流固耦合模拟,对45钢螺旋锥齿轮淬火冷却过程进行数值模拟,研究淬火介质流速对淬火结果的影响。结果表明,热流固耦合模拟和传统模拟的冷却曲线与试验测量的最大相对误差分别为9.2%和7.4%,且更加准确地预测淬火介质流动情况下的温度分布,验证了该方法的准确性和便利性。当入口流速为2 m/s时,硬度达到最大值52.0 HRC,且残余应力主要为有利的压应力。

Abstract: Based on thermo-fluid-solid coupling simulation, quenching and cooling process of 45 steel spiral bevel gears was numerical simulated, and the influence of quenching medium flow rate on quenching results was studied. It is found that the maximum relative errors between the cooling curves of thermo-fluid-solid coupling simulation and traditional simulation and experimental measurement are 9.2% and 7.4%, respectively. Moreover, more accurate prediction of temperature distribution under quenching medium flow conditions is achieved, verifying the accuracy and convenience of this method. When the inlet flow rate is 2 m/s, the maximum hardness value is 52.0 HRC, and the residual stress is mainly favorable compressive stress.
