标准摘要
[中文适用范围]： 故障物理 (PoF) 是一种基于科学的可靠性方法，它使用建模和仿真来实现可靠性设计。该方法可以模拟故障的根本原因，例如疲劳、断裂、磨损和腐蚀。计算机辅助设计 (CAD) 工具已经开发出来，可以处理各种负载、应力、故障机制和位置。PoF 利用基本故障过程的知识，通过稳健的设计和制造实践来预防故障，其目标是：预先设计可靠性；在测试之前消除故障；提高现场可靠性；促进快速、经济高效地部署健康和使用监测系统 (HUMS)；改进诊断和预测技术和流程；以及降低运营和支持成本。本指南概述了执行 PoF 评估的方法、流程和优势。 [外文原描述]： The Physics-of-Failure (PoF) is a science-based approach to reliability that uses modeling and simulation to design-in reliability. This approach models the root causes of failures such as fatigue, fracture, wear, and corrosion. Computer-Aided Design (CAD) tools have been developed to address various loads, stresses, failure mechanisms and sites. PoF uses knowledge of basic failure processes to prevent failures through robust design and manufacturing practices, and aims to:Design-in reliability up front;Eliminate failures prior to testing;Increase fielded reliability;Promote rapid, cost effective deployment of Health and Usage Monitoring Systems (HUMS);Improve diagnostic and prognostic techniques and processes; and,Decrease operational and support costs.This guide provides a high level overview of the methodology, process and advantages to performing a PoF assessment.Cross Reference: IEEE1413
