文中研究了相变材料复合恒温构件在ＭＫ７１６３平面磨床热变形控制技术中的应用，在分析相变传热的基础上，讨论了包含相变过程的二维传热特性，并推导了其传热过程的泛函表达式；利用有限元法计算复合相变材料恒温构件机床立柱及磨头箱体的温度场和热位移值，并将之与实测值比较，二者基本吻合。实验结果对热变形控制具有重要的参考价值
In this paper, the application of phase change material composite thermostat component in the thermal deformation control technology of MK7163 surface grinder has been studied. Based on the analysis of phase transition heat transfer, the two-dimensional heat transfer characteristics including the phase transition process are discussed and the heat transfer Process of the functional expression; finite element method is used to calculate the temperature and thermal displacement of the composite phase change material thermostatic member machine column and grinding head box, and compared with the measured values, the two basically consistent. The experimental results have important reference value for thermal deformation control
