摘要: 摘 要:在分析防辐射孕妇服的基础上,通过具体实验测得了两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建立测试的仿真模型,可以仿真获得服装的屏蔽效能。最后,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的结果比较一致,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的增大,随着下摆开口的增大,服装的电磁防护性能呈下降趋势。而且,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小,已经起不到防护电磁辐射的作用了。

Abstract: Abstract Based on the analysis of the electromagnetic shielding clothing for pregnant women, the anti-electromagnetic property of two electromagnetic shielding vests for pregnant women are tested through specific experiment. According to the actual testing conditions, a simulation model is established by the three-dimensional electromagnetic simulation software Ansoft HFSS to obtain the shielding effectiveness (SE) of clothing. The effects of changes in body shape for pregnant women during pregnancy on the anti-electromagnetic property of clothing are analyzed through the simulation model. The results show that the simulation results are basically identical with the actual measurement results, and the model of testing clothing can be applied for the researches on the protective function for electromagnetic radiation. The study also shows that the changes in body shape for pregnant women will directly cause the increase of bottom opening, and then the anti-electromagnetic property of clothing shows a downtrend. When the bottom opening of clothing increases to a certain degree, the SE values of clothing under the irradiation of electromagnetic waves at different frequencies are very small, that is to say the protective clothing has no function to protect pregnant women from electromagnetic radiation.
