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。
In this paper, calculation results from Fluid-Structure-Interaction Finite Element Method (FSI-FEM) and the theoretical solution are examined on the cylindrical liquid container ease. The applicability of FSI-FEM is discussed. Results show that FSI-FEM is able to calculate the vibration characteristics and dynamic response of the liquid container accurately. This method can further be employed in predicting the dynamic characteristics and analyzing the seismic time history of complex FSI models.
