Research on Modeling and Analysis Technology of General Quality Characteristics Based on MBSE

Abstract

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”.
