摘要
实验通过分别测量无阻尼振动和受到阻尼振动时系统的实时受力,用Origin软件对实验数据进行非线性拟合,将两种情况下的角频率进行对比,得到了液体的阻尼系数,并给出了液体的粘滞系数。
The experiment measures the vibration period of undamped vibration and damped vibration systems by real time force respectively. The experimental data on nonlinear fitting using Origin software. Comparison the two cases, the damping coefficient of liquid and viscosity of the liquid are obtained.
