复杂设备健康度评估方法研究综述

随着装备系统集成化、信息化程度的提高,复杂装备的工作可靠性至关重要,对其进行健康状态评估有着重要意义;健康度是对装备健康状态进行定量评估的方法,相对于分级的健康状态评估,可以更加细致地反映装备退化状况,能为装备视情维修提供准确依据,近年来得到越来越多的关注;通过对近几年国内外涉及装备健康度评估方法的相关文献整理,综述了复杂装备健康度评估研究的发展现状和相关评估方法,并从部件级和系统级两个方面对各种健康度评估方法进行了分类阐述和优缺点分析;着重指出了复杂装备在健康度评估中存在的权重问题、样本不均衡问题和健康度与故障率相关性问题;结合复杂装备特点及该领域最新研究进展,提出了未来研究思路和发展方向.

Review of health assessment methods for complex equipment

With the improvement of equipment system integration and informatization, the reliability of complex equipment is very important, and it is of great significance to evaluate the health status of complex equipment. Health degree is a quantitative evaluation method for equipment health status. This paper summarizes the development status and evaluation methods of complex equipment health by sorting out the related literature at home and abroad in recent years, and classifies and analyzes various evaluation methods. The weight problem, sample imbalance problem and the problem between health degree and failure rate in health evaluation are emphasized. Combined with the characteristics of complex equipment and the latest research progress in this field, the future research ideas and development direction are proposed.
