PHM of Complex Engineering Systems-Methods and Applications

ABSTRACT

Prognostics and Health Management (PHM) is an important research direction in reliability engineering. With the large-scale deployment of sensors and the maturity of big data technology, PHM has been more and more widely used in complex engineering systems, and it has produced significant social and economic benefits. PHM generally includes the key tasks such as anomaly detection, fault diagnosis, health assessment, and remaining useful life (RUL) prediction. The new generation of machine learning methods represented by deep learning has played a central role in promoting the development of PHM in the big data environment. This report takes high-speed train key components and subsystems as examples, and presents the latest developments in our laboratory. These new methods have a certain degree of versatility, and can be extended to the key components of other types of engineering systems.

预测与健康管理(PHM)是可靠性工程的一个重要研究方向。随着传感器的大规模部署与大数据技术的日趋成熟，PHM在复杂工程系统中得到了愈加广泛的应用，同时也产生了显著的社会经济效益。PHM一般包括异常检测、故障诊断、健康评估、剩余可用寿命（RUL）预测等关键任务。以深度学习为代表的新一代人工智能方法对大数据环境下的PHM发展起到了核心推动作用。本报告以高铁、航空关键子系统与核心零部件为例，介绍了实验室在PHM方法研究上的最新进展。这些新方法具备一定的通用性，可探索在其他重点装备上的研发和应用。
