摘　　要：面向新一代飞机采用的高度集成系统架构及其在总装测试中带来的复杂性,针对传统测试工艺流程占据总装生产主线时间长、无法满足高效批产的现状,提出一种飞机总装分布式网络化综合测试环境,能在生产性试验中分层分级、高效全面地验证飞机机载系统功能和性能。基于总装阶段机载系统测试内容和测试效率的分析,构建了“机外测试–机上测试”的总装测试模式。该模式采用基于以太网的“控制集成–分布测试”的集散式架构,实现了机外子系统测试、整机集成协同测试的总装阶段多层级测试,以及多系统间测试参数的互联互通,解决了传统总装机上测试工作量大、机上故障率高及故障排查难的问题。以具有高度集成架构特点的飞管/飞控系统为典型研究对象,所搭建的总装生产线的分布式网络化综合测试环境,可使机上测试内容减少52%,机上故障率降低60%,故障排查效率提高89%,验证了总装分布式网络化综合测试环境的可行性和有效性。This research concentrates on the high integrated complicated system architecture and the complexities at final assembly test stage.It proposes a distributed-network integrated test environment for aircraft final assembly stage towards the current long-time taken of final assembly tests,which fails to meet the needs of efficient mass production of new generation aircraft.The proposed test environment has the capacity to verify the functionalities and performance of aircraft airborne systems at production stage in a hierarchical,comprehensive,and high-efficient way.This research designs a“off-aircraft test and on-board test”final assembly test mode based on the analysis of airborne system test contents and efficiency.This mode uses the distributed architecture of“control integration-distributed test”based on Ethernet,which satisfies the needs of off-aircraft sub-systems tests,overall-aircraft collaborative tests under multi-hierarchy test processes of final assembly.It links the test parameters of multiple systems,and solves the problems of large test volume,high failure rate and difficult troubleshooting in traditional tests of final assembly.The aircraft vehicle management&flight control system is selected as a typical case study as it is highly integrated.A distributed-network integrated test environment is built for final assembly to verify the feasibility and efficiency,which achieved 52%reduction in overall tests,60%reduction in failure rates,and 89%increase in troubleshooting efficiency.
