I/UCRC: Collaborative Research on Coupled Models for Prognostics and Health Management

拟议的研究旨在为如何收集和评估产品生命周期从设计到使用阶段的退化数据提供一个全面的框架。提出的框架将加强数据驱动建模和基于物理的建模技术概述在以前的预后研究。通过采用耦合模型方案，可以降低对数据质量和完整产品设计信息的要求。该方案可以在关键的旋转机械部件（如轴承）以及更复杂的部件和结构（如电动汽车电池）上进行验证。提出的工作是开发一种数据驱动和物理驱动相结合的故障预测模型，这有可能大大降低制造系统和工艺的成本。这项工作得到了行业咨询委员会以及该中心的个别行业成员的支持，并有可能扩大该中心的投资组合。该中心通过教师和本科生研究经验（RET和REU）项目积极让少数民族和女学生参与研究，并将通过拟议的努力继续这样做。

The proposed research seeks to provide a comprehensive framework for how to collect and assess degradation data over the product lifecycle from design to usage phases. The proposed framework will enhance both data-driven modeling and physics-based modeling techniques outlined in previous prognostic research. By using the coupled model scheme, the requirements for data quality and complete product design information can be reduced. The scheme can be validated on a critical rotary machinery component, such as a bearing, as well as for more complex components and structures, such an electrical vehicle battery.The proposed work on developing a combined data driven and physics driven model for fault prognostication has the potential to yield significant cost reduction in manufacturing systems and processes. The work is supported by the Industry Advisory Board as well as individual industry members of the center and has the potential to extend the centers portfolio. The center has actively involved minority and female students in its research through Research Experiences for Teachers and Undergraduates (RET and REU) projects and will continue to do so through the proposed effort.
