Simulation Study on Vibration Modes of Metal Thin-Walled Beam for Liquid Level Measurement in a Liquid Container
To accurately simulate the vibration modes of the metal thin-walled beam used for liquid level measurement in a liquid container,a finite element circular beam model of metal thin-walled beam is constructed.The constructed model is used to analyze the characteristic frequencies of the longitudinal vibration models of the metal thin-walled beam,so that the longitudinal vibra-tions of this metal thin-walled beam exposed to external stimuli can be accurately simulated.In this study,the distributed mass model of the circular beam is adopted to analyze the characteristic frequencies of first four longitudinal vibration modes of the thin-walled beam.To verify the effectiveness of the constructed model,the simulation results of the first four vibration modes of the metal thin-walled beam are compared with those of the theoretical model results,the experimental results of the metal thin-walled beam and the simulation results of the other two simulation models.The comparison results show that the simulation results of the circular beam model are highly consistent with the theoretical and experimental analysis results,and the simulation results are significantly better than the other two models.
