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进展。本课题研究的具体目标是将实体建模、铸件凝固模拟和计算机辅助制造软件集成为一个整体系统，生成用于铸件凝固模拟软件的热性能数据，研究高效的计算技术，并对利用热管装置控制凝固过程中的热流密度进行了研究。将采用分析和实验方法。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产业，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（密歇根大学）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 progress towards this overall goal. The specific objectives of the research in this proposal are to integrate solid modeling, casting solidification simulation and computer aided manufacturing software into a total system, to generate thermal property data for use in the casting solidification simulation software, to investigate high efficiency computational techniques, and to investigate heat flux control during solidification by means of heat pipe devices. Analytical and experimental methods will be employed. 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 improved efficiency and quality in castings manufacturing. The work complements joint research to be conducted at another university (University of Michigan).
