MODAL ANALYSIS OF CORIOLIS MASS FLOWMETER

Tong Meng, Ren Ping, Chen Ming

Abstract

Coriolis Mass Flowmeter (CMF) is true mass flowmeter, by measuring the Coriolis effect of a vibrating flow pipe. Dynamitic Analysis of CMF plays an important role in its design and application. Finite element modal analysis of CMF Assembly and flow pipe individually is presented in the paper. CAD Model of CMF Assembly is built in AutoCAD, and then imported into FEM software Msc. Marc, and rotated to generate solid FEM model. Lanczos method is adopted in the calculation. Effects of type of the flow pipe’s support are investigated. It’s presented the FEM calculations are agreed with the theory analysis of Euler beam.
