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。

Abstract: 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.
