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.

    本发明提供一种基于振动的多维飞机附件机匣健康评估方法,属于固定翼飞机健康管理技术领域。所述多维飞机附件机匣健康评估方法首先确定振动监测状态指标、确定飞行状态、确定影响飞附机匣健康状态的工作状态参数;其次,建立健康评估模型,并通过应用数据优化模型参数。相对于传统的飞机附件机匣健康监测功能,本发明提出的基于振动的多维飞机附件机匣健康评估模型,增加了可以直接反映飞附机匣健康状态的振动数据,增加健康监测的有效性;对振动数据按照不同的飞行状态、工作状态进行分析处理,并参考滑油监测结果,增加健康监测的准确性;健康指标综合所有可以体现飞机附件机匣的因素,能够进行趋势分析和故障诊断,提高飞机附件机匣健康监测的实用性。
