摘要
Abstract
The vibration characteristics of the Coriolis mass flowmeter in the fluid-structure coupling state were studied in order to solve the metering error problem.Taking a typical CMF300 Coriolis mass flowmeter in a pipeline station as an example,the fluid-structure coupling modal vibration analysis and experimental study of Coriolis flowmeter are carried out by using ANSYS finite element method.The results are as follows:1)the calculated natural frequency of the second order mode is the excited frequency of Coriolis mass flowmeter,and the natural frequency of the sixth order mode is the Coriolis force frequency;2)the excitation frequency of finite element modal analysis is 80.043 Hz,and that of experimental test is 83.820 Hz;3)the excitation frequency and driving frequency of CMF300 are tested,and the experimental results are in good agreement with the finite element model;4)the numerical model and modal test method can obtain the actual natural frequencies of different Coriolis mass flowmeters at each station.The research conclusion provides a theoretical basis for eliminating the external interference to the metering error of the flowmeter.关键词
