摘要
Abstract
With the development of the civil aviation industry,aircraft systems have become increasingly complex,highlighting the issue of lagging risk assessment in traditional static Failure Mode and Effects Analysis(FMEA)within Prognostics and Health Management(PHM).To address this,this research focuses on the PHM requirements of civil aircraft,analyzes the shortcomings of traditional FMEA in fault modeling and dynamic monitoring,expands its functional modules,and constructs a dynamic risk assessment framework and model.This enables real-time updating and evaluation of severity,occurrence,detectability,and the Risk Priority Number(RPN).Using the variable-frequency AC electric pump in an aircraft hydraulic system as a validation case,the results demonstrate that this method can assess risk indicators in real time and with high accuracy.It provides a new approach to overcoming the limitations of traditional static FMEA and contributes to improving aircraft predictive maintenance and operational support capabilities.关键词
