摘　　要：航空电子全双工交换式以太网(AFDX)是在新一代大型飞机上应用的新型航空数据总线;AFDX已成为国内外先进民用飞机的核心总线,对其开展广泛深入的研究是非常必要的;针对AFDX性能和适航性研究的需要,首先建立了一套AFDX实验系统,在此基础上,采用Visual C++开发了AFDX应用程序;在实验系统上,该应用程序通过大批量数据发送、接收,验证了AFDX应用程序设计的正确性,在此基础上,通过对数据帧总数及字节数的统计分析,进一步验证了AFDX网络传输的可靠性,并为研究AFDX的确定性、可靠性等提供了大量的测试数据,满足了设计需求。AFDX is a new aviation data bus, which has been put into use in the new generation airplanes. AFDX is becoming the core bus of the data transmission in new airplanes, so it is of great significance to carry out the extensive research of AFDX. In the light of the need for the research of performance and airworthiness of AFDX, the experimental system is built up firstly, on the basis of which an application program is developed by the way of using C＋＋ programming language under the environment of VS. NET. In the experimental system, the application program verifies the correctness of the AFDX application design through amounts of data sending/receiving, and further veri ties the reliability of AFDX network transmission through the statistical analysis of the amount of frames and bytes. The application program also provides a large number of testing data to research the performance of AFDX, such as certainty, reliability and so on, which meets the design requirements.
