摘要
用数值仿真方法分析雷电流波形对建筑物遭雷击时室内磁场分布的影响。介绍了数值仿真方法并实验验证其有效性。在多种雷电流波形下对室内磁场分布进行计算和比较 ,发现雷电流的波头时间对磁场分布的影响很大 。
This paper investigates the influence of lightning current waveform on magnetic fields in a building struck by lightning through numerical simulation. The effectiveness of the simulation method was validated experimentally on scaled models. Magnetic field simulations are carried out under different lightning current waveforms. It is found that the rise time of the wavefron has a significant influence on the magnetic fields, but the influence of the shape of the waveform is negligible.
