Computer Aided Design for Casting and Solidification Technology (CADCAST)

本提案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的研究，这些研究在实现这一总体目标方面取得了成功进展。本课题研究的具体目标是完成一个模拟金属铸件凝固的计算机软件包的开发，并提高该软件包对过程控制的实用性。计算机模拟包将有助于铸件的设计和铸造制造过程。新的研究将探讨使用声发射传感来监测和控制铸造过程和铸造质量。此外，将开发用于软件包的实验数据，将研究金属-模具壁膨胀率，以预测模具图案几何形状与最终铸件几何形状之间的关系，并将研究高效计算技术。所提出的研究结果应提供有用的方法和软件的一个重要的美国行业，即铸造行业，并应有助于提高效率和质量的铸件制造。这项工作补充了将在另一所大学（阿拉巴马大学）进行的联合研究。

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).
