中文摘要：

为了有效评估地铁列车司机室在高频电磁环境下的安全性,利用基于有限元法的三维电磁仿真软件（HFSS）,构建B型地铁列车无线通信天线电磁辐射条件下的司机室高频电磁环境模型（其中人体模型为坐姿,由人头、躯干和四肢组成,人头模型由头皮、颅骨和大脑3层组织构成）,研究地铁司机的职业电磁暴露问题。结果表明：当天线的输入功率达到其最大值50 W时,人体模型的比吸收率最大值为0.523mW·kg-1,电场强度为11.96V·m-1,磁场强度为0.23A·m-1,皆低于国际非电离辐射委员会制定的职业电磁暴露限值;说明在此电磁环境下,司机室内的高频电磁辐射不会对地铁司机的健康造成危害。

英文摘要：

In order to effectively evaluate the safety under high frequency electromagnetic environment in the driver＇s cab of subway train, by using the three-dimensional electromagnetic simulation software （HF- SS） based on finite element method, the high frequency electromagnetic environment model of the driver＇s cab of B-type subway train under the electromagnetic radiation of wireless communication antenna was established to study the occupational electromagnetic exposure of subway train driver. In which, sitting posture was adopted for the human body model composed of head, trunk and limbs. The human head part was comprised of scalp, skull and brain. The results showed that, when the input power of the antenna reached its maximum of 50 W, the specific absorption rate of human body model was 0. 523 mW kg-1 , the strength of electric field was 11.96 V m-1 and the intensity of magnetic field was 0. 23 A m-1 , which were all lower than the limit values for occupational electromagnetic exposure constituted by the International Commission on Non-Ionizing Radiation Protection （ICNIRP）. It demonstrates that under such electromagnetic environment, the high frequency electromagnetic radiation in driver＇s cab is not a substantial health hazard to subway train driver.
