为实现铸件凝固过程快速模拟

首次提出动态边界条件计算法。并根据传热学中的相似理论

推导出毕渥准则修正式

通过对典型铸件的计算分析

证明采用上述动态边界条件的快速模拟法比传统模拟法节省计算机内存和机时60～80%

计算出的凝固时间的相对误差仅为3.69%。

In order to fulfil the high-speed numerical simulation of casting solidification processes

the Dynamic Boundary Condition Calculation is proposed first time. On the basis of the Similitude Theory in the heat transfer

the authors put forward the Biot Criterion Amendment Formulae. The experiments show that comparing with the traditional simulation methods

it is able to have the used computer storage and time cut down by 60

and the relative error of the calculated solidification time is only 3.69%.
