【摘要】 科里奥利质量流量计(CMF)是一种海洋石油和天然气工业广泛应用的仪器。确立了一种运用有限元软件ADINA进行CMF流固耦合振动分析的数值模拟方法,并用直管CMF的实验数据和分析数据相比较,验证该方法的可行性和准确性。在此基础上,提出两种弯管型CMF模型,用文中确定的数值模拟方法对其进行结构尺寸以及检测点布置对灵敏度的影响分析。该数值模拟方法为新型CMF的计算机辅助设计指明了方向。更多还原

【Abstract】 Coriolis Mass Flowmeter(CMF) is a widely used instrument in the field of offshore oil and gas industry.This paper developed a numerical simulation method for finite element vibration analysis of fluid-structure interaction,which was proved correct by comparing the analytical data with the experimental data of the straight tube CMF.Then the curled shape CMF model proposed by this paper was taken for an example,some influencial factors on measurement sensitivity,such as the dimension of the tube and allocation of the detectors were analyzed by the new numerical simulation method.Such research could point out the way for the computer-aided design of new CMF.更多还原
