Numeerical Calculation and Test of the Influence of Environmental Vibration on Coriolis Flowmeter

Abstract

Abstract Coriolis mass flowmeters are resonant meters. In this paper, the intrinsic mode of the CMF300 model Coriolis flowmeter under fluid-structure interaction is calculated numerically, and the excitation mode and Coriolis force mode of the Coriolis mass flowmeter in the working state are analyzed. According to the results of modal analysis, the harmonic response analysis of the flowmeter was carried out, and the displacement, stress, and strain response curves of CMF300 under the action of excitation force of different frequency loads were obtained. It provides ideas for the modeling and design of Coriolis mass flowmeters in the future.
