摘要
碳纤维复合材料在很多领域得到广泛应用,尤其是航空航天领域。为了研究雷电对于碳纤维材料的间接效应,以民用客机为应用背景,使用CST2017软件,选择TLM(传输线矩阵)时域求解器,对带有缝隙的立方体模型进行了仿真计算。得到了雷电流分量A波和H波作用下,航空铝合金材料和碳纤维复合材料模型的表面电流分布、内部电磁场分布以及内部三类电缆的电磁耦合规律。结果表明,碳纤维材料较之金属材料的屏蔽效能较小,线缆感应电流大小受雷电流参数影响显著,扭绞和屏蔽能有效减少电磁干扰。这些结果可以为飞机雷电间接效应防护提供参考。
Carbon fiber composite materials are widely applied in many fields, especially in aerospace field. In order to research the indirect effect of lightning on carbon fiber material, the research took the civil airliner as the application background, and then the cube model with slot was simulated CST2017 software and TLM(transmission line matrix) time-domain solver. Under the A wave and H wave of lightning current component, the surface current distribution, internal electromagnetic field distribution and electromagnetic coupling regularity of three kinds of cables in the model of aviation aluminum alloy material and carbon fiber composite material were obtained. Following conclusions can be drawn from simulation results. The shielding effectiveness of carbon fiber is less than that of metal material. The induced current in cable is significantly affected by the lightning current parameter. The twisting and shielding can effectively reduce the electromagnetic interference. These results can give a reference to the protection of lightning indirect effect on aircraft.
