摘要
利用圆柱体在自制圆弧轨道上的弱阻尼运动测量阻尼因数.通过Tracker视频分析软件对阻尼运动视频进行分析,得到运动曲线,并利用Origin软件对运动曲线进行拟合,根据拟合曲线方程得到阻尼因数的测量值.本实验可对阻尼因数的测量提供参考.
The damping factor was measured in the weak damping motion of the cylinder on the self-made circular arc track.The video of the damping motion was analyzed by the Tracker video analysis software,and the motion curve was obtained and fitted by the Origin software.The damping factor was measured according to the fitting curve equation.This study could provide a reference for the measurement of damping factor.
