摘　　要：采用有限元分析软件ANSYS建立了近似人体的二维仿真模型,分析计算了在500 k V交流输电线路下工频电场对人体的影响,得出了人体感应电场及总感应电流的分布情况.仿真结果表明,无论人体接地与否,人体最大感应电流密度和人体内部最大电场强度均小于国际非电离辐射防护委员会(ICNIRP)规定的安全限值.The finite element analysis software is applied to establish an approximate human body 2-D model,the effects of power frequency electric field generated by 500 kV AC transmission lines on human body is analyzed and calculated. The distribution pattern of induction electric field and the induced current of human body is worked out. The results of simulation showthat whether the human body grounded or not,the max induced current density and the max internal electric field intensity are both less than the safe limits set by International Commission on Non-Ionizing Radiation Protection（ ICNIRP）.
