本文介绍了在考虑金属材料热物理特性变化情况下建立转子预热计算模型。作者从圆柱体热传导一维非线性微分方程出发,考虑了导热系数与温度的变化关系,加热介质
This article describes the calculation of the rotor preheating model taking into account changes in the thermal physical properties of the metal material. Based on one-dimensional nonlinear differential equations of cylindrical heat conduction, the author considers the relationship between the thermal conductivity and temperature, and the heating medium
