摘　　要：采用科氏流量计弯曲振动测量粘度其关键在于准确得到粘性力消耗的能量与粘度的关系。采用微元分析方法,系统分析了测量管中轴向无流速时弯曲振动中液体粘性力造成的能量损耗,推导出测量管谐振时消耗功率与粘度的数学模型,并用实验进行了验证。The key of using bending vibration of Coriolis mass flowmeter to measure the fluid viscosity lies in accurately obtained the relationship between the energy consumed by viscous forces and the viscosity. Using micro-element analysis method, the energy loss within the fluid is analyzed systematically when there is no flow rate in the axial of measuring tube, the mathematical model between the power consumption and viscosity is derived when measuring tube in a resonant state and verified by experiment.
