基于FMECA的飞参采集器维修性信息分析

Maintainability Analysis of Flight Data Generator Based on FMECA

摘要:

维修性作为决定产品维修品质与寿命、周期和费用的关键因素之一,它是一种设计属性且日益受到各方的重视,特别是航空维修系统；某型飞机进入修理阶段需要开展机载设备维修设计,针对该机装备的新型飞参采集器的维修准备中保障资源确定无输入依据信息的问题,提出了一种基于FMECA的信息分析方法；首先介绍了FMECA,其次分析了采集器的任务功能、功能组成结构及可靠性框图,再次根据各模块的故障模式及其影响、危害性和基本维修措施等内容编制FMECA维修性信息分析表；最后进行危害性分析并绘制出危害性矩阵图,找到了对采集器危害性最大和影响较大的故障模式,避免了传统维修性分析方法的盲目性和主观性,表明FMECA的信息分析方法在航空产品维修性分析中有较好的应用和推广价值。

Abstract:

Maintainability is one of the key factors, it decides the product quality,life span, maintenance cycle and cost.It is a kind of design attributes and increasingly brought to the attention of the parties, especially in the aviation maintenance system.The plane entered the stage of repair, aerial equipment needed maintenance design,Aiming at the problem of no input information of determine the collector maintenance support resources,Put forward a method based on information of FMECA analysis.First introduces the FMECA,secondly analyses the collector task function, composition structure and the reliability block diagram, again according to the failure mode and effect of each module, harmfulness and basic maintenance measures, Prepare a list of the FMECA the maintainability information analysis.Finally analyzing harmfulness and map the harmfulness of matrix,To avoid the blindness and subjectivity of traditional maintainability analysis method, That information analysis method of FMECA in the aviation product maintainability analysis has good application and popularization value.
