The invention provides a multi-dimensional aircraft accessory casing health assessment method based on vibration, and belongs to the technical field of fixed-wing aircraft health management. The multi-dimensional aircraft accessory receiver health assessment method comprises the following steps: firstly, determining a vibration monitoring state index, determining a flight state, and determining a working state parameter influencing the health state of an aircraft accessory receiver; secondly, establishing a health assessment model, and optimizing model parameters through application data; compared with a traditional aircraft accessory receiver health monitoring function, the vibration-based multi-dimensional aircraft accessory receiver health evaluation model provided by the invention has the advantages that vibration data capable of directly reflecting the health state of the aircraft accessory receiver is added, and the effectiveness of health monitoring is improved; the vibration data is analyzed and processed according to different flight states and working states, and the accuracy of health monitoring is improved by referring to a lubricating oil monitoring result; the health indexes are integrated with all factors capable of reflecting the aircraft accessory receiver, trend analysis and fault diagnosis can be carried out, and the practicability of aircraft accessory receiver health monitoring is improved.
