Abstract
To study the electromagnetic field distribution characteristics when lightning current acts on aerospace composite structural parts,two lightning current pulses of different frequency bands are select-ed.We use CST electromagnetic simulation combined with experiments to compare and analyze the elec-tromagnetic field distribution characteristics on the surface and internal space of structural parts under the action of H-component and 8/20 μs standard pulse.The results show that the electromagnetic character-istics will vary when different frequency bands of lightning current waveforms are applied.For the mag-netic field characteristics,the carbon fiber composites under the action of H-component of the lightning current show obvious skin effect,resulting in the reduction of the peak value of the internal induced mag-netic field and the extension of the peak time;for the electric field characteristics,under the action of H-component of lightning current,the high-frequency electric field relies more on the establishment of the high-frequency magnetic field.The wavefront stage of the electric field waveform shows attenuation oscillation characteristics.关键词
