摘要
用信号发生器驱动蜂鸣片在真空泵油中产生受迫振动,通过测量液体中振动物体的谐振频率求得液体阻尼系数,进而确定了液体黏度.
Buzzer is driven by signal generator to create forced vibration in vacuum pump oil, the damping coefficient of the liquid could be extracted by measuring the resonance frequency of the vibrating object in the liquid, the liquid viscosity could be determined accordingly.
