摘要
航空装备的可靠性、安全性、测试性分析在工程应用中存在大量重复性工作,如重复开展FMEA等;传统FMEA存在很多管理和技术问题,且GJB/Z 1391—2006中给出的功能及硬件FMEA方法自身也存在一定的技术缺陷,导致FMEA应用效果差,甚至很多外场真实故障应用传统FMEA是无法分析出来的。本文首先从MBSE角度着手,充分融合产品研制流程和通用质量特性的设计分析评估过程,以产品功能作为通用质量特性的输入,基于功能故障逻辑建模分析,对飞控系统功进行案例应用。结果表明:基于MBSE的通用质量特性建模分析技术可有效避免重复工作,并能解决“两张皮”问题。
The reliability,safety and testability analysis of aviation equipment has a lot of repetitive work in engineering application,such as repeated failure mode and effect analysis(FMEA).However,traditional FMEA has many management and technical problems,and the functions and hardware FMEA methods given in GJB/Z 1391—2006 also have certain technical defects,resulting in poor FMEA application effects,and even many real failures in the field cannot be analyzed.This article first starts from the perspective of system engineering.In the model-based systems engineering(MBSE)mode,it fully integrates the product development process and the design analysis and evaluation process of general quality characteristics.The product function is used as the input of general quality characteristics,based on the functional failure logic modeling analysis.And carry out case application of flight control system functions,which can effectively avoid duplication of work and solve the problem of“two skins”.
