铸造过程数值模拟的研究发展现状
摘要:随着电子计算机技术的飞速发展,铸造工艺计算机辅助设计CAD,铸件凝固过程数值模拟CAE等多项技术已大量应用于生产实际。工业发达国家制定的下一代制造(NGM)计划所提出的十项关键基础技术中就包括建模与仿真。铸件的凝固过程数值模拟技术主要包括铸件及其工艺的几何造型、三维传热数值计算技术和缺陷判据这三部分,并可对凝固过程中出现的缺陷进行预测,评判铸造工艺设计的合理性,以减少工艺实验的次数,降低工艺设计成本,提高工艺出品率和合格率。

Research on the development status of numerical simulation of casting process
Abstract: with the rapid development puter technology, computer aided design of foundry technology CAD, numerical simulation of casting solidification process of CAE and many other technology has been widely applied in actual production. Industrial developed countries to develop the next generation manufacturing (NGM) are ten key basic technology plan put forward in includes modeling and simulation. The casting defects puting technology and criterion of this three part of numerical heat transfer, including 3D geometric modeling and Simulation of the process of casting solidification process numerical, and to predict the defects that appear during the solidification process of casting process design, evaluation of rationality, in order to reduce the times of experiment process, reduce the design cost, increase the process yield and the qualified rate.
