摘 要: 研究了利用强迫振动扭摆方法测量液体粘滞系数的原理.由标准滞弹性体的Voigt型三参数模型确定了测量系统的基本参量,从而证明了利用强迫振动扭摆测量液体粘滞系数的四参数模型的正确性. Abstract The principle of the viscosity measurement of liquids with a forced vibration torsion pendulum is studied in this paper.The parameters of the testing system was determined by a 3 parameter model containing a Voigt unit,and the feasibility of the corresponding 4 parameter model of the measuring system,in which a liquid sample has been introduced to measure its viscosity,is then verified.It is proposed,based on the experimental results,that the measuring system is reliable.
