摘　　要：考虑了流固耦合效应在储液容器跌落分析中的作用,采用耦合欧拉-拉格朗日(CEL)方法模拟液体在储液容器跌落过程中的惯性效应以及液体对容器所产生的侧向液动压力,综合考虑了流固耦合效应对储液容器跌落过程中容器本身的变形和动态响应的影响。结果表明,该方法可以较为准确地评价容器的安全性和结构设计的合理性,也为同类结构的设计评价提供参考。Considering the fluid-structure interaction effects in the analysis of liquid storage container dropping, coupling Euler-Lagrange （CEL） method is used to simulate the inertia effect of fluid and the lateral hydraulic pressure to the container, and the fluid-structure interaction effects on the deformation and dynamic response of the container during the process of dropping is considered. The numerical result shows that the method can provide a more accurate evaluation of vessel safety and structural design. Therefore, the CEL mentioned in the paper also provides a reference design evaluation method for the same structure.
