Simulation Research on Electromagnetic Radiation Effects of Electric Vehicle on the Occupant Health 2016-01-0135

Nowadays researches of automotive electromagnetic field mainly focus on the component level and electromagnetic compatibility, while there is a lack of relevant studies on internal electromagnetic environment of the vehicles. With the increasingly complex internal electromagnetic environment of the vehicle, people are increasingly concerned about its potential impact of human health. This article researches on a type of electric vehicle and the occupants and analyses its electromagnetic radiation effects on human health. Firstly, considering the characters of Pro/E, Hypermesh and FEKO, the “Characteristics grouping subdivision” method is used to establish the entire vehicle body FE model. According to the requirement of MOM/FEM method, the entire vehicle model is optimized to be a high quality body model with simple construction and moderate grid size. Secondly, Using transfer vehicle electromagnetic radiation function of the simulation method, simulation study was made on the electromagnetic radiation characteristics of the subsystems. Then simulation results and vehicle electromagnetic radiation limit in GB18387-2011 standard are compared and analyzed. At last, a human body electromagnetic model is established based on the biological electromagnetism. The electromagnetic radiation absorbed dose of occupants in vehicles are studied. At the same time, the specific absorption ratio (SAR) of occupants on different location in vehicles is compared and analyzed.
