整车重点区域场强仿真与分析

Simulation and Analysis of Field Strength in Key Areas of Vehicle

为了准确分析自由场抗扰波形下车内重点区域的电场强度,建立自由场测试天线、整车模型、暗室环境等仿真模型,计算车内5个重点区域的场强。最后通过实车测试,验证了计算结果的准确性,可判定自由场抗扰仿真能够较好地预测车内场强分布。

In order to accurately analyze the electric field intensity of key areas in the vehicle under the free field immunity waveform.The simulation models of free field test antenna,vehicle model and darkroom environment are established to calculate the field strength of five key areas in the vehicle.Finally,the accuracy of the calculation results is verified by real vehicle test.It can be judged that the free field immunity simulation can better predict the field intensity distribution in the vehicle.
