Abstract

Circuit experiment is a very important professional basic course for students of electrical experiments. Experiment study is further validation of theoretical study and supplement. If the deviation between the experimental data and the theoretical value is large, it will not verify the theoretical value, instead it will make students feel puzzled. So if there is a problem, how to solve it? This paper is mainly from the experiment, numerical simulation and theoretical values to compare and determine the accuracy of measuring damping coefficient method under the condition of under-damped RLC second-order circuit. It also analyzes the reasons of the error, and then put forward the damping coefficient correction method.

二阶电路衰减系数的误差分析

电路实验是电学实验专业一门非常重要的专业基础课。实验研究是对理论研究的进一步验证和补充。如果实验数据与理论值偏差较大，不但不能验证理论值，反而会让学生感到困惑。那么如果出现了问题，该如何解决呢?本文主要从实验、数值模拟和理论值三个方面进行比较，确定了欠阻尼条件下RLC二阶电路阻尼系数测量方法的精度。分析了误差产生的原因，提出了阻尼系数的修正方法。
