【摘要】：以圆柱形含液容器振动为例,比较流-固耦合有限元方法与理论解的计算结果,分析有限元方法的适用性。结果证明,流-固耦合有限元方法能够准确有效地计算含液结构的振动特性与动力响应问题,可以利用有限元模型预测复杂流-固耦合结构的动力特性并对其进行地震时程分析。
[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.
