摘要
本文从理论和实验上分别研究了三线摆在大角度摆动下的周期与角度的关系,设计制作了仪器摆动角度测量装置。实验发现了三线摆摆动过程中的平动,在实验条件下,发现平动周期约是摆动周期的5倍。我们还研究了三线摆阻尼的实验情况,推导出了在有阻尼的情况下摆动周期的公式。
This paper experimentally and theoretically studied relationships between the period of three line pendulum swinging in the large angle and Swing angle. The measuring device of swing angle was made. The translation was found in the process of the three line pendulum swing. The translation period is about 5 times swing period, in addition, the situation of three line Pendulum damping was also studied. The periodic formula of damping situation was given.
