摘　　要：AFDX协议以及航空总线布局的复杂性使得建立一套完整的地面仿真测试系统尤为重要,良好的网络仿真系统可对网络的关键部件进行物理仿真、地面测试,大大缩短了网络的建设周期,降低了系统的维护成本。介绍了一种AFDX网络仿真系统的设计方案,建立了以端系统、交换机为核心,以仿真、监控、加载、管理系列AFDX网络设备为辅助的AFDX网络仿真测试系统,并详细说明了各个组成部分,用户可通过本平台对AFDX网络通信机制、原理以及应用进行评估和理解,运用仿真监控功能透彻理解AFDX网络设备的数据流、运行方式和工作原理,方便进行问题定位及故障排除。The complexity of AFDX（Avionics Full Duplex Switched Ethernet） protocol and aviation bus layout makes it is particularly important to establish a complete ground simulation test system. A good network simulation system provides physical simulation and ground test for the key network components, it ′ s greatly reducing the construction cycle of network and the maintenance cost of the system. This paper introduces a kind of design scheme of AFDX network simulation system which is established mainly on the end system and the switch and assisted by AFDX network equipment such as simulation, monitor, load and management. It discusses the various components of the simulation system in detail. Users can evaluate and understand AFDX network communication mechanism, principle and application through this platform, thoroughly understand AFDX network data flow, operation mode and working principle of equipment. It is useful to help users location the problem and resolve trouble shouting through simulation function.
