摘要

基于电磁振荡以及高压尖端放电原理，利用特斯拉线圈模拟自然界中的雷电及其磁场。利用ＴＥＳ?５９３三维电磁测量仪对所产生的雷电磁场进行测量，探究了放电频率ｆ、放电脉宽Ｉ与雷电磁场的关系。通过原创的“暂态循迹仿真分析法”对不同高度下的磁场分布情况进行测量和仿真，进一步探究雷电磁场分布与雷电距地面高度的关系。

Abstract:

Based on the principle of electromagnetic oscillation and high-voltage tip discharge , tesla coil isused to simulate lightning and its magnetic field in nature.The lightning magnetic field is measured by TES-593hree-dimensional electromagnetic measuring instrument,and the relationship between discharge frequency fdischarge pulse width I and lightning magnetic field is explored.Using the original method called simulationanalysis with transient tracking ,the magnetic field distribution at different heights can be simulated.Therefore.the relationship between lightning magnetic field distribution and lightning height from the ground is exploredon this basis.

Key words: lightning magnetic field simulation and measurement simulation analysis with transient tracking
