Comsol仿真软件在“电磁兼容”课程实验中的应用

Application of Comsol Simulation Software in the Course Experiment of Electromagnetic Compatibility

随着电子产品中的电磁兼容问题越来越受到关注,“电磁兼容”理论已成为电气技术人员必备的专业基础知识,也是测控专业的学生不可或缺的能力之一。针对“电磁兼容”理论中概念抽象、公式多、学生理解困难等问题,通过优化实验内容,采取基于问题需求牵引式、互动式的教学方式,将Comsol仿真软件引入学生的实验中去。以“飞机天线串扰电磁兼容仿真实验”设计为例,说明将仿真软件用于电磁兼容课程实验的全过程。结果表明,该实验方式从多角度综合考虑了电磁兼容性的问题,有利于培养学生的理论知识,以及分析问题、解决问题的能力。

With the increasing attention to the problem of electromagnetic compatibility in electronic products,Electromagnetic Compatibility theory has become a necessary professional basic knowledge for electrical technicians,and it is also one of the indispensable abilities of students majoring in measurement and control.Aiming at the problems of abstract concepts,many formulas and difficult understanding of students in the Electromagnetic Compatibility theory,COMSOL simulation software is introduced into students’experiments by optimizing the experimental content and adopting the traction and interactive teaching method based on problem needs.Taking the design of“aircraft antenna crosstalk electromagnetic compatibility simulation experiment”as an example,this paper explains the whole process of applying the simulation software to the course experiment of Electromagnetic Compatibility.The results show that the experimental method comprehensively considers the problem of electromagnetic compatibility from multiple angles,which is conducive to training students’theoretical knowledge and the ability to analyze and solve problems.
