摘　　要：基于多导体传输线理论,应用了MATLAB和CST进行数学建模仿真和实物建模仿真,对比分析了不同模型下的单根线缆对非屏蔽双绞线的串扰,验证了CST实物仿真模型的有效性和准确性。研究了屏蔽双绞线屏蔽层双端悬空时,飞机上直流电源接通或断开对飞机ARINC429数据传输线产生的串扰;并分析了单根线缆与ARINC429数据传输线在不同间距和不同平行敷设长度情况下的线间串扰。对飞机ARINC429数据传输线的实际安装过程有一定的指导作用,为将来复杂线缆结构串扰分析提供了一定的研究基础。Based on the theory of multi-conductor transmission line, the crosstalk between a single cable and a UTP （unshielded twisted pairs） cable was studied. The MATLAB and CST were employed to do the theoretical calculation and modeling respectively, and the comparison result proved the validity and accuracy of the proposed model. Based on the UTP model, the shielding layer was used to build the STP （shielded twisted-wire pairs ） model according to the ARINC429 specification, and the crosstalk which caused by a large voltage transient happening on the adjacent power line on the aircraft was further analyzed. The distance and length of the cables were chosen as the main factors for studying the impact on the crosstalk. The study played an important guiding role for actual ARINC429 data bus installation on the airplane, and paved the way for analyzing the crosstalk effect of complex cable structure in the future.
