Abstract：Rotating machinery is an important component of mechanical equipment, with complex internal structural complexity and strong coupling degree between its key components and subsystems. It is prone to easy failure under long-term complex working conditions. Once the failure occurs, it can lead to the decline overall performance of the machine, and even cause significant economic losses or personal injury. Therefore, the research on the health status assessment of rotating machinery has become one of the key points in the development of modern national defense and industrial equipment. Based on the requirements of health management and intelligent maintenance of rotating machinery, the status and role of health status assessment in intelligent operation and maintenance of mechanical equipment are firstly discussed. Secondly, the concept of health status assessment technology, the classification of status levels, and assessment indicators are introduced. Thirdly, typical assessment methods based on knowledge and experience, model-driven, and data-driven methods are illustrated. Fourth, the research achievements in the evaluation of health status of typical rotating machinery in recent years are reviewed, such as pumps, bearings, gearboxes, and aircraft engines. Finally, based on technical challenges and development trends faced by research on health status assessment methods, the development direction of health status assessment methods for rotating machinery is discussed and prospected.
