为研究不同材料组成的多层储罐类结构温度场分布，基于该类结构的几何特征和温度场分布特点，将结构简化为球壳部分、圆筒部分和平板部分的组合，进而给出了简化分析模型。从热传导方程和能量守恒原理出发，应用温度边界条件的转换，得出温度等效边界条件。在研究单层材料温度场的基础上，应用递推方法和层间边界条件的连续性，给出了多层不同材料组成的球壳部分、圆筒部分和平板部分的温度场分布的理论简化解。以某典型工程为例，通过该方法与 ABAQUS 软件数值模拟结果的比较，验证了其计算精度。

The temperature field distribution of the multi-layer storage tank was studied.The simplified cal-culating model was presented by combining together a cylinder,a sphere and a plate according to the tank's geometrical and temperature field characteristics.The equivalent temperature boundary conditions,by u-sing the boundary conditions with form converted,were derived based on the heat transferring equation and the principle of conservation of energy.The temperature field distribution of multi-layer storage tank parts,such as the cylinder,the hemisphere and the plate,was given by simplified theoretical calculation method based on the temperature field of the simple-layer part.Numerical results of a representative pro-ject based on the software ABAQUS were plotted so as to verify the accuracy of the theoretical solution by comparison.
