摘　　要：在分析防辐射孕妇服的基础上,通过实验测得2件防辐射孕妇马甲的电磁防护性能,并且根据实验条件利用三维电磁仿真软件Ansoft HFSS建立测试仿真模型,获得服装的屏蔽效能。利用该仿真模型分析了孕妇不同孕期体型变化对服装电磁防护性能的影响。研究结果表明,服装电磁屏蔽效能测试模型的仿真结果与实际测定结果比较一致,该模型能够用于电磁辐射防护功能方面的研究。研究还表明,孕妇体型的急剧变化会直接导致防辐射孕妇服下摆开口增大,随着下摆开口的增大,服装的电磁防护性能呈下降趋势。当防护服下摆开口增大到一定程度时,服装对不同频率电磁波的屏蔽效能值都非常低,已经无法起到防护电磁辐射的作用了。Based on the analysis of the electromagnetic protective clothing for pregnant women,the electromagnetic protective effects of two electromagnetic shielding vests for pregnant women are tested through specific experiments.According to the actual testing conditions,a simulation model is established using the three-dimensional electromagnetic simulation software Ansoft HFSS,which can simulate the electromagnetic shielding effectiveness（SE） of clothing.The impact of body shape change of women during pregnancy on the electromagnetic protective effect of the clothing is analyzed through the simulation model.The results show that the simulative results are basically identical with the actual measurement results,and the model is suitable for researches on shielding against electromagnetic radiation.The study also shows that the change in body shape of pregnant women will directly cause the increase of bottom opening,which results in the decrease of electromagnetic protective effect of the clothing.When the bottom opening of clothing increases to a certain extent,the SE values of the clothing under the radiation of electromagnetic waves at different frequencies are very small,that is,the protective clothing has no function to protect pregnant women against electromagnetic radiation.
