中文摘要：

为解决车载装置在不同路面的接地问题,我们研制了可迅速安装和撤收的便携式接地装置,并选取一种组合在不同岩土介质地面上进行了实验,测得各自的冲击接地阻抗。然后,采用时域有限差分法对实验装置进行了数值分析,得出了该接地装置冲击接地阻抗的时域特性。与实验结果进行对比的结果表明,两者具有较好的一致性。

英文摘要：

In order to solve the problem of grounding of vehicle-mounted device, we has developed a type of portable grounding device which can be quickly installed and folded. And we selected one combination to test on the ground in different geotechnical media and got the transient grounding resistance (TGR) of each. Then the numerical analysis of experimental device was did by finite difference time domain (FDTD) method and got the TGR time-domain characteristic of the grounding device. Compared with the results of the experiment, it shows that both have good consistency.
