随着计算机硬件条件的改善,铸造过程数值模拟技术有了长足的进步和发展,国内外此类商品化软件不断完善并对实际生产起着越来越重要的作用。本文介绍了铸造过程数值模拟技术的一些基本思路的原理;并列举了华铸CAE软件在实际生产中的一些应用,应用表明该软件能够很好地预测充型过程中的卷气、夹渣等缺陷以及凝固过程中缩 With the improvement of computer hardware conditions, the numerical simulation technology of foundry process has made great progress and development. Such commercialized software at home and abroad is constantly improving and playing an increasingly important role in actual production. This paper introduces some basic ideas of numerical simulation of foundry process and some applications of Huazhu CAE software in practical production. The application shows that the software can predict the curl, slag inclusion and so on Defects and shrinkage during solidification
