Engineering Deployment Teaching Initiative: Mechanical System Design for Reliability -- Technology Deployment

9410680 Mahadevan确实需要设计工程师能够将设计决策过程与产品可靠性联系起来，以支持定量评估，更有效地使用实验以及生产过程和变量的工程规范。设计工具在设计过程中易于集成也是很重要的。部署策略在部署技术的定义和评估中有效地利用了工业。它还利用计算机网络、讲习班和会议将技术迅速传播到大学和工业界。要开发的教育材料包括对方法的完整描述、以视图形式呈现的材料、简化的电子表格计算工作模型、一个带有几个概率设计分析选项的计算机程序，以及示例问题。这项工作将通过教育基础设施为工业机械设计界部署基于可靠性设计分析的计算工具的现成技术。已开发的技术已被发现是通用的机械系统的可靠性，并已被证明是直接可用的设计过程中，没有广泛的知识统计和概率方法。它使设计人员能够计算设计不确定性，如任何合理的设计极限条件下的失效概率，并将许多这样的设计极限条件组合成系统可靠性的广义估计。在每一步中，设计师都能直接得到关于产品不可靠性和设计可信度的关键驱动因素的反馈，从而促进重新设计以提高可靠性。

9410680 Mahadevan There is a real need for design engineers to be able to link the design decision making process with product reliability in a way that supports quantitative evaluation, more effective use of experiments, and engineering specifications on production processes and variables. It is also important that design tools be easy to integrate in the design process. The deployment strategy makes effective use of industry in the definition and evaluation of the deployed technology. It also uses computer networks, workshops, and conferences for rapid dissemination of the technology to universities and industry. The educational materials to be developed include a full description of the methodology, presentation material in the form of view graphs, simplified working models for spreadsheet calculations, a computer program with several options for probabilistic design analysis, and example problems. This effort will deploy a ready technology of computationally-based tools for reliability-based design analysis to the mechanical design communities in industry through an educational infrastructure. The developed technology has been found to be generic for mechanical systems reliability and has been shown to be directly usable in the design process without extensive knowledge of statistics and probability methods. It enables the designer to compute design uncertainties such as the probability of failure for any sensible design limit condition and to combine a number of such design limit conditions into a generalized estimate of system reliability. At every step, the designer is given direct feedback on the critical drivers of product unreliability and design confidence levels, facilitation re-design for enhanced reliability.
