摘要
功能危险分析(Functional Hazard Analysis,即FHA)是一个分析和评估过程,主要是以分析评估系统内或设备中潜在的故障及所发生故障的影响。它通过分析来确定系统操作中可能发生的故障,并判断故障对人员的危害。FHA是系统安全评估中的重要内容,是其他安全性分析项目的基础,更是民用飞机满足适航审定要求必须完成的分析项目。通过对功能危险分析方法在飞机刹车系统应用过程的分析,总结了该方法应用时遇到的难点以及应对办法,并简要说明了分析结果。
Function Hazard Analysis（FHA）is an evaluation procedure that analyzes and assesses the effects of potential failures in a system or equipment.It determines by analysis the effect of failures on system operation,identifies failures critical to personnel safety.FHA is an important part of the Safety Assessment Process,the basis of other safety analysis and obligatory analysis item in order to meet airworthiness certification.The hard parts during the application of FHA in brake system were summarized and the answers to these problems were presented.The result of analysis was briefly demonstrated.
