Title:: Finite Element Quantitative and Visual Analysis of Electrostatic Shielding

摘要:: 针对传统静电屏蔽现象研究多局限于定性描述，即缺乏对屏蔽空间的量化描绘，也未能系统揭示材料电导率的影响，本研究采用有限元仿真技术，结合静电场与电流场模型，系统量化分析了理想导体与有限电导率导体对静电屏蔽效能的影响。仿真可视化结果清晰呈现了静电屏蔽从理想模型到实际应用场景的物理演化过程，初步解释了材料电导率影响屏蔽效果的规律特征，为静电屏蔽现象的量化研究及实际工程应用提供了精准的分析方法与理论支撑。

Abstract:: Traditional studies on electrostatic shielding are mostly limited to qualitative desc＜x＞riptions, lacking quantitative characterization of shielded regions and failing to systematically reveal the influence of material conductivity. Using finite element simulation combined with electrostatic field and steady current field models, this work quantitatively analyzes the shielding performance of ideal conductors and conductors with finite conductivity. The visualization results clearly show the physical evolution of electrostatic shielding from ideal models to practical application scenarios, and reveal the regulation law of material conductivity on shielding effectiveness. This study provides accurate analytical methods and theoretical support for the quantitative research and engineering applications of electrostatic shielding
