Study of Mechanical Model of Linear Tube Coriolis Mass Flow Meter

本文对单直管型科里奥利质量流量计的测量原理进行了详细论述。基于典型的单检测管结构,将它简化成简支梁,分析其受力,推导了单直管型科氏质量流量计的力学模型、振动频率和旋转角速度的计算公式。另外,本文还给出了检测电路图,对信号进行处理。

The measuring principle was investigated for the linear ruble Coriolis direct mass flow meter in detail.The mechanical model of the linear ruble Coriolis direct mass flow meter was deduced by analyzing under stress,and formula of vibration frequency and angular velocity of rotation were established in the paper,based on a typical linear ruble structure and it was sim- plified.In addition, the circle measurement principle of the linear ruble Coriolis mass flow meter was prese- nted in the paper,in order to measure and treat signal.
