| 摘要: |
| 以民机舱门全寿命周期的安全使用为目标,提出了一套完整的民机舱门机构功能安全性分析设计方法。首先以民机舱门事故统计为基础,分析其主要故障模式,通过对相关适航条款的分析与解读,确定民机舱门主要故障模式的安全性指标;接着采用故障模式影响分析和故障树分析方法对各故障模式开展可靠性建模计算,同时对影响程度较大的故障模式进行共因故障分析;最后,将计算结果与安全性指标进行对比分析,如不符合要求,还需进行安全性改设计。该分析方法适用于飞机设计全过程,可指导舱门机构优化设计。 |

| Abstract: |
| The goal of this paper is the safe use of civil aircraft cabin door in its life cycle,and a complete set of analysis and design methods of the mechanism safety of civil aircraft cabin door is presented. First,based on the accident statistics of civil aircraft cabin door,the major failure mode is analyzed and confirmed. And through analyzing and interpreting of the relevant airworthiness rules,the safety indicators of the major failure mode are confirmed. Then,the analysis of the effect of failure mode and failure tree analysis method are adopted to model and calculate the reliability of each failure mode. Finally,the calculated results are compared with security indicators;safety improvement design needs to be made if they do not meet the requirements. We believe that our analysis method is suitable for the aircraft design process,and can guide the optimization design of the cabin door. |
