一种易于实现的电磁兼容方法

针对车辆电磁兼容性问题,研究了不同方位接地与不接地时电磁波照射车辆时表面电流分布,得出接地后最大表面电流均有一定程度降低,对于高斯脉冲入射方向与车轴成30°角时,垂直面内接地后电流强度由111.57 A/m降为17.322 A/m,水平面内接地后电流强度由22.566 A/m降为11.458 A/m。测试结果表明:接地是降低车辆表面电流行之有效的方法,对于提高车辆在高威胁复杂电磁环境中的生存能力具有重大的意义。

An Easy Method for Electromagnetic Compatibility

For Vehicle electromagnetic compatibility issues. The paper is researched electromagnetic wave radiation vehicles surface current distribution in the case of different azimuth grounding and not,and find that the maximum ground surface current is reduced to a certain extent in the first condition,when the Gaussian pulse incident direction of the axle at into 30 degrees,the strength of current to reduce to 17.322 A/m by 111.57 A/m in the vertical grounding ,and that reduce to 11.458 A/m by 22.566 A/m in horizontal grounding.The results show that the ground is a effective methods to improve the vehicle in high threat complex electromagnetic environment.
