利用Tracker研究气垫导轨上弹簧振子运动
|
摘要
文章利用Tracker软件的自动追踪功能,对气垫导轨上弹簧振子的运动进行分析,得到滑块运动的数据及图像。在考虑弹簧质量的情况下,利用Tracker软件捕捉到的数据,定量地分析不同时段系统的机械能,验证在短时间段内弹簧振子系统的机械能守恒。在系统长时间的运动过程中,考虑系统中的能量损失,在Tracker分析得到滑块运动的v-t图形的基础上使用软件自带的拟合功能,对长时间段内滑块运动图像进行函数拟合,进而分析计算出气垫导轨上弹簧振子做阻尼振动的阻尼系数。
Using automatic tracking of Tracker,we analyze the motion of the spring oscillator in the air cushion guide,and get the slider movement data and image.Considering the mass of the spring,the mechanical energy of different periods of time is quantitatively analyzed by the data captured using Tracker software,and the mechanical energy conservation of spring oscillator system in a short period of time is verified.The energy loss is considered during the long time movement of system.Based on the v-t graph of the slider movement obtained by Tracker,It is viable to using the automatic fitting function in software to fit the slider movement image for a long period.Then the damping coefficient of the spring oscillator on the air cushion rail is analyzed and calculated.
