摘　　要：利用FEKO建立适合电磁仿真的坐姿人体模型和汽车车身模型,对电动汽车的主要电磁辐射源进行简化和仿真,得到在电机、DC/DC变换器、天线这些激励下的车内电磁环境,并对人体及主要器官进行比吸收率（SAR）的仿真计算。结果表明,在100－900 MHz时,车内人体比吸收率都满足限值,其中SAR较大的组织是皮肤与大脑,这为电动汽车中的人体电磁安全研究提供了参考依据。A seating human model and a car body model,suitable for electromagnetic simulation,were established in FEKO.Main electromagnetic radiation sources of electric vehicles were simplified and a simulation was carried out.The electromagnetic environment inside the car was obtained under the electromotor,DC/DC convertor and antenna.SAR of human body and main organs were also computed.The result shows that SAR of occupants inside a car satisfies the limit when the frequency is the commonly used communication frequency 100-900 MHz,the SAR of skin and brain is much larger,providing references for researches on personal electromagnetic safety in electric vehicles.
