摘　　要：聚四氟乙烯/聚酰亚胺复合绝缘航空线是飞机中用量较大的一类线缆,其载流量对飞机的电气线路互联系统(EWIS)设计具有极其重要的作用。基于电磁热多物理场耦合模型,采用COMSOL软件对6 AWG、10 AWG、16 AWG这3种规格的聚四氟乙烯/聚酰亚胺复合绝缘航空线进行载流量建模仿真,并与实测数据和SAE AS50881H:2023中的数据进行对比,验证仿真结果的正确性。该研究可为航空线缆EWIS设计提供一种简单有效的方法。PTFE/PI combined insulated aerospace wires are extensively used in aerospace vehicles,and current carrying capacity is an important factor for the design of electrical wiring interconnection system(EWIS).Based on multi-physics coupled model,three specifications of wires,6 AWG,10 AWG and 16 AWG,were chosen to simulate current carrying capacity by COMSOL.Besides,simulation results were compared with measured data and the data from SAE AS50881H:2023,to verify the correctness of simulation.The study could provide a reference for the design of aviation EWIS without numbers of experiments.
