摘　　要：研究铸铁件消失模铸造充型过程中界面推移的规律,将消失模铸造的充型过程视为模样在热作用下气化消失的过程。给出了一种消失模铸造充型过程数值模拟的人工神经网络算法,利用计算机进行的铸铁件消失模铸造充型过程的数值模拟结果与相应的实测值基本一致。The paper studies the interface shifting law in the process of demould cast for iron casting, looks upon the process filling the mould in demould cast as that of the mould disappearance with heating, and gives a artificial nerve network algorithm for numerical simulation on the process filling the mould in demould cast. The results obtained by use of computer numerical simulation on the process filling the mould in demould cast for iron casting basically areconform to the measured values.
