摘　　要：提出一种联合仿真方法,先使用COMSOL Multiphysics软件仿真目标装置的电场分布,计算出各种条件下的电场分布;然后在基于Matlab的轨迹仿真中使用上述电场仿真结果代替描述电场的方程。这种Matlab与COMSOL Multiphysics联合仿真不仅提高了轨迹仿真的准确度,还可以应用在各种复杂的电场条件下。本文应用联合仿真方法对基本的静电纺丝、添加了环形和平行辅助极板的静电纺丝轨迹进行了联合仿真和实验验证。在此基础上,采用联合仿真方法对双喷头双极性静电纺丝轨迹进行了仿真和实验验证。结果表明,联合仿真结果与实验结果吻合得很好。Electrospinning is a widely used technique to synthesis nanofiber materials. In order to further study the electrospinning process, software simulation method was introduced in many reports.There are two kinds of software, and each of them has its advantage： Software Matlab is good in mathematical computing, and COMSOL Multiphysics can perfom accurate calculation for complicated electric fields. However, the relevant discription for electric fields in Matlab simulation was inacurate. A new method of joint simulation combining Matlab and COMSOL softwares together was used in this report： In the Matlab simulation process, the electric field equation was replaced by COMSOL calculation results. Compared with the Matlab simulation results, the joint simulation results are much close to actual conditions.This method also overcame the inconvenience（incapability） of electric field description in Matlab simulation and provided a solution to simulate fiber trajectories in complicated electric fields, such as parallel or circular auxiliary electrodes, respectively. The joint simulations were carried out for the electrospinning with one and two nozzles respectively. The electrospinning experiments prove that the joint simulation can predict fairly well the experiment results.
