阻尼振动中阻尼系数的研究

在传统的大学力学教材与其他有关力学知识的书中,对于阻尼振动中阻尼系数的研究已屡见不鲜,并且有许多学者与老师都对此进行了分析和研究,并取得了不错的理论结果,但只是利用了传统的试验方法来测定阻尼振动中的阻尼系数,在文章中,利用实验测得的数据进行数值拟合来计算空气阻尼和磁阻尼的阻尼系数,得出了令人满意的结果,与传统实验手段比较起来更为准确。

In the traditional teaching materials of mechanics in colleges and other related books , there are many studies on the damping coefficient in damped vibration. Besides, many scholars and teachers made analysis and re-search on it, and obtained good theoretical results. However, they only used traditional test method to measure the damping coefficient. This paper calculates the air damping and magnetic damping coefficient through numerical fitting of experimental data, and obtains satisfactory results, which are more accurate compared with the traditional experi-mental method.
