Computer Aided Design for Casting and Solidification Technology (CADCAST)

这项建议的总体目标是开发金属铸造过程的计算机辅助设计和控制方法。这一建议延续了先前在实现这一总体目标方面取得成功进展的研究成果。这项研究的具体目标是完成计算机软件包的开发，以模拟金属铸件的凝固过程，并提高该软件包对工艺控制的实用性。该计算机模拟程序包将帮助设计铸件和铸件制造工艺。新的研究将探索使用声发射传感来监测和控制铸造过程和铸件质量。此外，将开发用于软件包的实验数据，将研究金属模壁膨胀以预测模具型型几何形状与所产生的铸件几何形状之间的关系，并将研究高效率的计算技术。建议的研究结果将为美国一个重要的行业，即铸造业提供有用的方法和软件，并应有助于提高铸件制造的效率和质量。这项工作是对另一所大学(阿拉巴马大学)进行的联合研究的补充。

The overall goal of this proposal is the development of computer aided design and control methodology for the metal casting process. This proposal continues previous research which made successful progress towards this overall goal. The specific objectives of the research in this proposal are to complete the development of a computer software package to simulate solidification of metal castings and to improve the utility of the package for control of the process. The computer simulation package will aid in the design of the casting and of the casting manufacturing process. New research will investigate the use of acoustic emission sensing for monitoring and control of the casting process and casting quality. In addition, experimental data will be developed for use in the software package, investigation will be made of metal-mold wall dilation for predicting the relationship between mold pattern geometry and the resulting casting geometry, and high efficiency computational techniques will be investigated. The results of the proposed research should provide useful methodology and software for an important U.S. industry, i.e., the foundry industry, and should contribute to improve efficiency and quality in castings manufacturing. The work complements joint research to be conducted at another university (University of Alabama).
