摘要
军用飞机健康评估在工程实际中存在应用困难的问题。以军用飞机为研究对象,开展包括面向任务的能力分析、基于故障劣化的功能分析以及参数化的健康评估等研究,得到基于任务分析的"飞机-任务功能-影响参数"两级映射作为健康评估的对象;综合利用劣化度、严酷度及极大熵改进区间层次分析法等多种方法,得到飞机健康状态评估结果。结合具体实例及参数分析结果,表明该评估方法可信度高,具有较高的工程实用价值。
The military aircraft health assessment has the problem of difficult application in engineering practice.The military aircraft is taken as the research object of health assessment,including task-oriented capability analysis,function analysis based on fault degradation and parametric health assessment.The two-level mapping of“aircraft-mission function-impact parameters”based on mission analysis is obtained as the object of health assessment.The degradation,severity and maximum entropy modification are comprehensively utilized.The results of aircraft health assessment are obtained by interval analytic hierarchy process and other methods.In combination with the specific example object and parameter analysis results,this assessment method has high reliability,and high engineering practical value.
