摘　　要： 针对静电纺丝形成过程受电场分布影响较大这一特性,本文对平板式、向下凹球帽式、向下凸起球帽式基底的电场强度和电势进行数值仿真分析,分别对后两类进行了不同曲率半径的建模分析。结果表明曲率半径为800 mm向下凹球帽式的基底在其附近可以产生较为均匀的电场分布和电势分布。进一步对曲率半径800 mm下凹基底不同偏心距电场分布分析,偏心距对基底电场的影响较大。为静电纺丝电场参数优化提供依据。 There is great relationship the forming progress of electrospinning and the electric field’s distribution.For this feature,this papersimulate and analyze electric field of there kinds of receiving devices substrate:flat plate type,ball socket of downward concave,ball socketof downward convex.About later kinds of receiving devices the paper do modeling analysis on different radius of curvature.The results showthat ball socket of downward concave which radius of curvature is800mm can get relatively uniform electric field and electric potentialdistribution.Uniform electric field distribution is beneficial for forming a relatively uniform electrospinning fiber membrane.This paperanalyzes the electric field distribution of receiving devices which eccentric distance of the experimental device is different when receivingdevices is downward concave and it’s radius of curvature is800mm.This will provide the basis for optimization of electrospinning electricfield parameters.
