摘　　要：1553B总线系统已广泛应用于飞行器中,为确保大系统的电磁兼容性,有必要开展总线连接器的屏蔽效能测试研究。针对当前总线连接器转移阻抗测试方法的局限,提出了一种新的搭接简单、测试方便的快速测试方法。通过大量的测试试验,获取了该型总线连接器的转移阻抗特性;并通过比照分析测试数据与经验公式,验证了所提出的测试方法的有效性。The 1553B bus system has been widely used in aircraft, so it is necessary to analyze shielding effectiveness of the bus connectors to ensure electromagnetic compatibility of the whole system. Transfer impedance is an effective attribute of shielding efficiency of connectors. Based on the analysis of limit of current test methods, a simple and convenient workbench setup has been developed to test the transfer impedance of bus connectors. Through a lot of experiments, the transfer impedance characteristics have been acquired, meanwhile, the simulation results of shielded bus connectors based on the measuring data have been proven to be consistent with the experience formula analysis, which proves validity of the proposed method.
