STTR Phase I:Heat treatment process modeling and simulation tools

这一小型企业技术转移研究(STTR)第一阶段项目将确立伍斯特理工学院(WPI)开发的CHT(计算机辅助热处理)技术商业化的可行性。拟议的研究将：(1)开发基于知识发现的数据挖掘工具，以发现隐藏的炉膛模型参数和规则；(2)开发校准技术，以便能够对每个单独的炉膛进行炉膛分析，从而提高模型的准确性；(3)开发基于网络的服务模型，使客户能够广泛使用工具；以及(4)将当前的CHT系统转换为基于网络的系统，以促进面向服务的商业模式。热处理工艺是一种制造工艺，它决定了材料的性能对产品质量的影响。在WPI卓越热处理中心(CHTE)的资助下，开发了一种加载炉子模拟技术，用于模拟复杂的热过程和组织演变，以预测材料的性能。利用生产数据对模型进行了验证。该方法可进一步用于优化热处理工艺，提高能源效率，减少加工时间和生产成本，实现热处理零件的零变形和均匀。

This Small Business Technology Transfer Research (STTR) Phase I project will establish the feasibility of commercialization of CHT (Computer-aided Heat Treatment) technology developed at the Worcester Polytechnic Institute (WPI). The proposed research will: (1) develop knowledge discovery based data mining tools to uncover hidden furnace model parameters and rules; (2) develop a calibration technique to enable furnace profiling for each individual furnace which will improve model accuracy; (3) develop a web-based service model to enable broad customer beta use of the tools; and (4) convert the current CHT systems into web-based systems to facilitate the service oriented business model. Heat treatment process is a manufacturing process which determines the materials properties contributing to the product quality. Under WPI Center for Heat Treating Excellence (CHTE) sponsorship, a loaded furnace modeling technique has been developed for simulating the complex thermal process and microstructure evolution for predicting material properties. The models have been validated with production data. This approach can be further used to optimize heat-treating processes, improving energy efficiency, reducing process times and production costs, and achieving zero distortion and uniformity in heat-treated parts.
