摘要

以瞬态傅里叶导热微分方程为基础

提出了一种处理多材质铸造过程边界条件的通用化方法

自主开发了基于有限元法（FEM）的多材质铸造过程温度场数值模拟软件。计算了工字型件空冷过程温度场以及多材质复杂铝合金铸件凝固过程温度场

并与ANSYS以及华铸CAE的模拟结果进行了对比。对比结果表明

空冷过程的温度场的最大相对误差为2.130‰

凝固过程温度场的最大相对误差约为2.064%

验证了温度场程序的正确性以及可靠性。

Abstract

Based on the mathematical model of the transient heat conduction equation

ageneral method of treating multi-material boundary conditions was presented

and a temprature-field numerical simulative program for multiply materials based on finite element method（FEM）was developed.The temperature field of a typical I-shaped specimen during air cooling and a complex aluminium alloy casting during solidification process were calculated by the self-developed program

which was well agreement with the ones calculated by ANSYS and InteCAST.The maximum relative error of temperature field during air cooling is 2.130‰

and the maximum relative error during solidification is 2.064%

so the correctness and the reliability of the temperature program have been verified.
