Dropping Accident Analysis of Liquid Storage Container using Finite Element Method

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.
