Finite Element Simulation On Dropping Impact Of Liquid Storage Container

The liquid storage container is used in many industries. The safety design in dropping impact is very important for the liquid storage container. Coupled Euler-Lagrange method (CEL) in Finite element package—ABAQUS/Explicit is used in current work. The effects of different dropping angles, different dropping heights, different thicknesses of the container, and the volume of the liquid on the dropping impact of the liquid storage container are studied.In chapter1, the background and significance of the dropping impact of the liquid storage container is introduced. The basic theories of the fluid-structure interaction and the main researches on the liquid storage container are reviewed.In chapter2, the basic theories which the simulation is used are discussed. First, this chapter simply describes CEL technical development and its applications. Second, this chapter discussed how to solve the fluid dynamic equations which are referred as N-S equation and the coupling method in CEL. At last, the chapter introduces the constitutive equation of the solid and the equation of sate of the fluid.In chapter3, the model sizes, the material property, the meshing and the boundary conditions are introduced. Then, the CEL method is validated with comparison the published literatures. Based on the CEL method, the effects of different dropping angles, different dropping heights, different thicknesses of the container, and the volume of the liquid on the dropping impact of the liquid storage container are studied. The maximum equivalent plastic strain and the reaction forces are studied in detail, which is useful for the safety design of the liquid storage container.
