【摘要】 针对电磁场理论难学、难懂和难用的问题，设计了两平行输电线路的场分布电磁场实验。介绍了应用电轴法得到的电位分布解析解，ANSYS仿真建模的方法和模拟电荷法求电位和电场强度的公式及求解步骤，对3种方法的结果进行比较，验证了3种方法的正确性。实验以解决实际问题为出发点，设置分层次的实验任务，引导学生采用理论分析、仿真建模和数值分析的方法完成实验。培养了学生应用电磁场理论分析实际问题的能力，使学生充分体会到电磁场理论和工程软件ANSYS对实际工程问题的指导意义及数值算法的重要性。更多还原

【Abstract】 Aiming at the problem that electromagnetic field theory is difficult to learn, understand and use, a field distribution electromagnetic field experiment of two parallel transmission lines is designed.This paper introduces the analytic solution of potential distribution obtained by the electric axis method, the method of ANSYS simulation modeling, and the formula and solving steps of potential and electric field strength obtained by the charge simulation method. The results of the three methods are compared to prove the correctness of the three methods. The experiment takes solving practical problems as the starting point and sets hierarchical experimental task to guide students to use theoretical analysis, simulation modeling and numerical analysis to complete the experiment. It has exercised students’ ability to apply electromagnetic field theory to analyze practical problems, so that students can fully appreciate the guiding significance of electromagnetic field theory and engineering software ANSYS on practical engineering problems, as well as the importance of numerical algorithm. The work of this paper provides a new idea for the reform of electromagnetic field experiment teaching.更多还原
