民用飞机机载产品FMEA和关键特性分析的集成应用

Application of integration of FMEA and key characteristics analysis on civil aircraft airborne product

摘要:

为解决关键特性分析在民机机载产品开发过程中缺少定量分析方法及分析流程的问题，首先总结行业现状明确改进方向，然后分析了失效模式及影响分析（FMEA）与民机机载产品开发过程的关系、行业标准对关键特性的定义、FMEA和关键特性分析的关系。通过FMEA方法对失效影响的评估识别关键特性，建立了FMEA和关键特性分析的集成模型、基于FMEA方法的关键特性分析流程；通过建立功能关键特性与关键特性的映射关系，为产品详细设计过程中对关键特性的分析提供了方法。对民机机载雷达传动装置的应用研究表明，FMEA和关键特性集成方法能够指导产品开发实际应用。

Abstract:

In order to solve the problem that quantitative analysis method and analysis process for key characteristics (KCs) analysis are lacked, current research status is analyzed, relationship between Failure Mode and Effect Analysis (FMEA) and civil aircraft airborne product development process, standard definitions of KCs, relationship between FMEA and KCs analysis are also analyzed. Furthermore, the integrated model and process of FMEA-KCs analysis are built, KCs are identified by evaluating failure effects through FMEA method and mapping relationship between functional KCs and KCs. It is demonstrated through an example that the integration of FMEA and KCs analysis contributes significantly to product development application.
