采用有限元数值模拟的方法对金属型铝合金活塞凝固过程的温度场分布进行了计算。前后处理采用商品化软件，用所开发的接口程序实现计算主程序与前后处理软件间数据传递与处理。为了验证计算结果的准确性，在铸件及铸模上各选一个参考点，对参考点温度值随时间的变化，进行了现场测定，并将计算结果与实测值做了对比，最后分析了误差产生的原因。

In this article, the authors simulate the distribute oftemperature field of the solidificaiton process of piston in metal model by the finite element method. Pre-process and post-process are finished by a commercial software Interface programme connects the oomputing programme with the pre-process and post-process software. A point in the cast piece and a point in the cast modl are chosen as referencial points, the results of the two points' temperature distrbute by computing and testing are compared: Causes for the clearance are analysed.
