中文摘要：

IVHM技术是近年来新兴的健康管理技术，能够从系统层面有效实现对飞行器健康状态的监控和管理。健康评估与仿真作为IVHM的核心技术，受到国内外研究者的广泛关注。在综合大量国内外文献的基础上，介绍了IVHM技术发展现状，并总结了IVHM系统的结构。按照构建健康评估和健康仿真模型的原理将飞行器健康评估和健康仿真技术分为基于机理的模型和基于数据统计的模型两类，分别分析了两种技术的应用现状，对尚存问题和技术难点做了剖析。

英文摘要：

The technology of IVHM is an emerging health management technology, which can effectively realize the health monitor and management of vehicles in system - level. As the key technologies of IVHM, health assess- ment and simulation draw extensive researchers＇ attention at home and abroad. Based on the overview of lots of rele- vant literatures, the status of IVHM is introduced and structure of IHVM system is summarized. According to the de- signing principles of health assessment and health simulation models, both the flight health assessment and health simulation can be divided into two main groups： model based on principle and model based on statistic. This paper analyses the research status of industrial application, existing problems and technical difficulties of the technologies.
