The objective of this research project is to develop advanced and cheap-to-evaluate interpolation models that emulate the expensive computational fluid dynamics (CFD) and finite element analysis (FEA) solvers incorporated in a patented physics-based component life prediction tool called XactLIFE system developed in-house by the industrial partner (LPTi- Life Prediction Technologies Inc.). LPTi provides prognostics based life cycle management services for gas turbine engine parts utilizing the XactLIFE system. Going forward as part of a new product offering to their clients, LPTi aims to custom build the XactLIFE system for specific engines (with preselected critical parts). This would need the substitution of the CFD and FEA solvers present in the XactLIFE system with interpolation models to achieve real-time simulation and to avoid the need for embedding expensive CFD and FEA solvers in the customized engine specific XactLIFE systems. The proposed interpolation models will be developed utilizing computational intelligence techniques by the research team from the University of Waterloo in close collaboration with the technical experts and engineers from the industrial partner. The interpolation models will be trained with simulation results corresponding to a limited set of operating conditions (defining an envelop) and then they will be used to predict the results for any operating condition within the envelop in real-time. This research project will significantly impact the capability and range of application for the XactLIFE system in terms of its efficient and cost-effective applications to various industries for predictive maintenance of engine components and mechanical structures. The success of this project will enable the industrial partner to create new source of revenue generation and reach out to new clientele.

该研究项目的目的是开发高级且廉价的评估插值模型，这些模型模仿昂贵的计算流体动力学（CFD）和有限元分析（FEA）求解器（FEA）求解器，该模型纳入了基于专利的物理学的组件生活预测工具中，称为Xactlife系统，称为Xactlife系统，由工业合作伙伴（Lpti-Life Prediction Technologies Inc.）内部开发。 LPTI利用XACTLIFE系统为燃气轮机发动机零件提供基于预后的生命周期管理服务。作为向客户提供的新产品的一部分，LPTI旨在定制针对特定发动机（带有预选的关键零件）的XACTLIFE系统。这将需要使用插值模型替换Xactlife系统中存在的CFD和FEA求解器，以实现实时模拟并避免需要 将昂贵的CFD和FEA求解器嵌入定制引擎特定于XACTLIFE系统中。拟议的插值模型将使用滑铁卢大学的研究团队与工业合作伙伴的技术专家和工程师密切合作，利用研究团队的计算智能技术开发。插值模型将通过与有限的操作条件集（定义信封）相对应的仿真结果训练，然后它们将用于预测信封内任何操作条件的结果。该研究项目将严重影响XACTLIFE系统的功能和应用范围，以其对各个行业的高效且具有成本效益的应用来预测维护发动机组件和机械结构。 该项目的成功将使工业合作伙伴能够创建新的收入来源并与新客户联系。
