摘要
等长的双线悬挂的平板在水平方向的摆动是一个复杂的问题。本文首先从理论上研究了平板在水平方向的小角摆动属于简谐振动。其次,利用安装Phyphox软件的智能手机及其光传感器功能测量该平板的运动周期。并改变放置在平板中央的铁球的质量,测量该系统摆动周期的变化规律。并用origin绘制周期图,以此计算了平板摆动的周期。实验结果与理论结果符合得很好,这一研究对处理复杂系统的摆动问题提供了实验验证方法。
The horizontal swing of the flat plate hanged by two lines with equal length is a complex problem.We studied the small angular swing of the flat plate in horizontal direction,which belongs to harmonic vibration.Second,the swing frequency of the flat plate is measured by smartphone installed “phyphox” software and its light sensor.We changed the mass of the iron ball placed in the center of the plate and measured its swing cycle of the system.The measured data were obtainde and the period curves are plotted by Origin software to calculate the swing period of it.It is found that the experimental results are in good agreement with the theoretical ones.This work provides an experimental surport for dealing with the oscillations of complex systems.
