Reliability Analysis for AFDX Network based on Dynamic Fault Tree

摘要：

　　As the basis for comprehensive integration of the aircraft,AFDX network has been widely used in avionics network.AFDXs reliability analysis and verification is particularly important according to the requirements of airworthiness.The transmission process,components and functional contact between components of AFDX network is analyzed in this paper.Dynamic fault tree (DFT) is used to model AFDX network reliability according to network fault characteristics.This analysis process has two contributions for network reliability analysis.Firstly,the analysis of AFDX network failures is implemented to device-level,which is facilitated to quantitative calculations in engineering.Secondly,end system and switch system,the core subsystem in transmission of AFDX,are analyzed and modeled,besides fault of redundant network.
