摘　　要：针对科氏质量流量计因制造误差而影响测量准确度,以直管型科氏质量流量计为例,通过对科氏质量流量计进行动力学模型分析,得到模型系数、阻尼比、固有频率等参数,从而获得直管型科氏质量流量计在空管和通水状态下的动力学模型,并通过ANSYS仿真验证模型的有效性。In view of the measurement accuracy of Coriolis mass flowmeter affected by manufacturing error,taking straight tube Coriolis mass flowmeter as an example,through the dynamic model analysis of Coriolis mass flowmeter,the model coefficient,damping ratio,natural frequency and other parameters can be obtained,so as to acquire the dynamic model of straight tube Coriolis mass flowmeter under empty pipe and water flow conditions.The validity of the model is verified through ANSYS simulation software.
