介绍了基于平面有限元模型的冻结温度场数值反演及模拟方法,考虑冻结孔实际偏斜和测温孔实测温度数据,进行冻结温度场反演和预测研究。得到模拟计算结果与冻结工程中测温孔温度实测值有较好的一致性,说明冻结计算温度场分布规律有较高的精度。 The numerical inversion and simulation of freezing temperature field based on the planar finite element model are introduced. The actual deflection of the freezing hole and the measured temperature data of the temperature measuring hole are taken into account, and the inversion and prediction of the freezing temperature field are studied. The calculated results are in good agreement with the measured values ​​of the temperature of the temperature-measuring holes in the freezing project, which shows that the distribution of the temperature field in the freezing calculation has higher accuracy.
