为求解换热系数模型,以大量现场数据与热传递机制为基础,建立换热系数回归模型并使用ANSYS有限元软件对钢板冷却过程进行模拟,获取淬火过程中间数据。通过非线性回归算法对模型参数进行回归计算,最终取得整个淬火过程的换热系数公式。解决了现场无法测量淬火过程温度值,难以求解换热系数的难题。 In order to solve the heat transfer coefficient model, based on a large amount of field data and heat transfer mechanism, the heat transfer coefficient regression model was established and the steel cooling process was simulated by ANSYS finite element software to obtain the intermediate data of quenching process. Regression calculation of the model parameters by nonlinear regression algorithm finally obtains the formula of heat transfer coefficient of the whole quenching process. Solve the scene can not measure the quenching temperature, difficult to solve the problem of heat transfer coefficient.
