服装面料电磁防护性能的测试与模拟

为了消除或减少电磁波辐射对人体造成的危害，各种具有电磁防护功能的服装面料应运而生并得到迅速的发展，但是服装面料的电磁防护性能的测试费用一直较为昂贵．本文在研究织物电磁屏蔽原理的基础上，分析了服装面料的电磁防护性能与面料本身的电磁参数及厚度的关系．并且通过专业的电磁仿真软件Ansoft HFSS建立面料电磁屏蔽效能测试的仿真模型．将服装面料的电磁参数以及厚度值代入模型中，可以模拟测试获得服装面料的电磁屏蔽效能．这对于设计开发人员来说不仅可以减少昂贵的测试费用．加快开发的速度．还有利于设计出成本更低、防护性能更好的产品。

Measurement and Simulation of the anti-electromagnetic property of fabric

In order to eliminate or reduce the harm of human body caused by the electromagnetic radiation, various anti-electronmgnetic fabrics emerge as the times require and develop rapidly. However, the costs of fabrics for testing the anti-electromagnetic property are always very expensive. Based on studying the protective property of fabrics for electromagnetic radiation, this paper analyzes the relationship between the anti- electromagnetic property of fabric and the electromagnetic parameters and thickness of fabric itself. The simulation model of fabrics for testing the shielding effectiveness （SE）is established by the professional electromagnetic simulation software Ansoft HFSS and the simulation SE values of fabrics can be obtained by taking the electromagnetic parameters and thickness of fabrics into the model. For developers, the results of this paper can not only help to reduce the high test costs and accelerate the speed of development, but also be beneficial to design products with lower cost and better anti-electromagnetic property.
