Calculation of Electric Field Distribution in the Simulating Device for Animal Experiment

A main way to investigate the biological effects of 50Hz electromagnetic field is to conduct animal experiments by using the simulating device of 50Hz electromagnetic field. In order to determine the exposure strength of experimental animals in rearing cages in simulating device more accurately, the distribution of electric field should be simulated. Based on ANSYS, a software of finite element analysis, we simulated two-dimensional (2D) electric field distribution of the proposed simulating device of high voltage 50Hz electric field for a case when there were no rearing cages, and we validated those simulation results by comparison with actual measurements. Additionally, we simulated three-dimensional (3D) electric field distribution in the rearing cages for the cases when there was one rearing cage and when there were 8 rearing cages in the simulating device respectively. The simulation results showed that distribution of 50Hz electric field in rearing cage was not uniform when there were rearing cages in the simulating device, and the maximum difference was about 9kV/m. Therefore, based on the movement tracking of animals and the distribution of 50Hz electric field in rearing cages, the cumulative exposure dose of experimental animals could be determined accurately through integral method in order to increase the accuracy of experiments.
