摘　　要：采用孔板式电极代替传统针头,用Maxwell软件模拟静电纺丝装置的静电场分布,考察了孔板电极尺寸、厚度及孔间距等因素的影响。模拟结果表明：相对于传统的针头式电极系统,孔板式电极电场更加均匀稳定,电极尺寸及厚度影响静电场的分布,而孔间距对静电场几乎无影响。适宜的电极半径R=20~25 mm,厚度H=17 mm。A plate-holes spinneret needleless electrospinning equipment instead of needles spinneret was developed to study the electrostatic field distribution.The effect of plate-holes electrode size, thickness and hole spacing was analyzed using Ansoft Maxwell software .The simulation results show that plate-boles electric field distribution is more uniform and stable than needles electrode, the size of plate-holes electrode and thickness affect the distribution of electrostatic field, but the hole spacing has little influence on the electrostatic field.The best electrode size is the radius R= 20-25 mm and thickness H=17 mm.
