| 目的 研究金属复合板在冷却过程中的温度变化规律以及经过冷却后金属复合板的表面及内部温度分布规律。方法 利用二维有限差分法对金属复合板材冷却过程中的温度变化规律进行了分析，从理论上推导了使用等步长节点法求解温度的差分方程，通过设置合理的边界条件解决了金属复合板基板和复板接触界面互相影响的传热问题。结果 通过设置等步长节点的有限差分法计算得出金属复合板冷却过程的温度变化规律以及冷却后金属复合板的表面及内部温度分布，对比有限元软件模拟计算和有限差分程序计算结果，得出结论。结论 界面处温度高，越靠近两边温度越低，通过与有限元软件模拟计算作对比，验证了差分法计算的准确性。 |

| The work aims to study the temperature change law of metal composite plate during cooling and the distribution law of surface and inside temperature after cooling. The two-dimensional finite difference method was used to analyze the law of temperature change of metal composite plate during cooling, and the difference equation for solving the temperature by equal-step node method was theoretically derived. Reasonable boundary conditions were set to solve the heat transfer problem of the interaction between the metal composite plate substrate and the contact interface of the composite plate. Through the finite difference method with equal-step node, the law of temperature change of the metal composite plate during cooling and the distribution of surface and inside temperature after cooling were calculated. By comparing the simulation results of finite element software with those of finite difference program, a conclusion was drawn. The interface temperature is high, but the temperature closer to both sides is lower. Compared with the simulation calculation by finite element software, the accuracy of the difference method is verified. |
