[Abstract]:Taking the vibration of cylindrical liquid container as an example, the results of fluid-solid coupling finite element method and theoretical solution are compared, and the applicability of the finite element method is analyzed. The results show that the fluid-solid coupled finite element method can accurately and effectively calculate the vibration characteristics and dynamic response of liquid-containing structures. The finite element model can be used to predict the dynamic characteristics of complex fluid-solid coupling structure and to analyze its seismic time history.
