可视化静电场分布实验装置设计开发

Design and Development of Experimental Apparatus for Visual Electrostatic Field Distribution

根据静电场和极化原理,利用高压直流电源、不同形状电极、电机以及arudino单片机等器材,设计并制作了一种可视化静电场分布的实验教学装置。实现了对现教学用模拟法测绘静电场装置所用不同形状电极产生静电场的直接观测,以同轴柱面电极为例,实验现象结果与Comsol模拟结果相符,并基于该实验装置开发了其虚拟仿真实验,有效辅助大学物理实验教学的开展。

According to the principle of electrostatic field and polarization,a visual experimental teaching device of electrostatic field distribution was designed and made by using high-voltage DC power supply,electrodes of different shapes,motors and Arudino single-chip microcomputer.This device realizes the direct observation of the electrostatic field generated by different shape electrodes used in the current teaching simulation method to map the electrostatic field device.Taking the coaxial cylindrical electrode as an example,the experimental results are consistent with the Comsol simulation results.Based on this experimental device,the virtual simulation experiment is developed to effectively assist the development of university physics experiment teaching.
