The Dynamics of the Problem Modeling and Numerical Simulation of Liquid Sloshing in Liquid Storage Container

Based on acoustic models,the fluid can be modeled as an acoustic medium,discretized with acoustic elements,and the free surface of the fluid must be 'skinned' with membrane elements,and a grounded spring is attached to each node on the free surface of the fluid.Using the finite element package ABAQUS,weestablished the finite element model of 3D liquid sloshing in rectangular tank,analysed the eigenfrequencies and the modals of liquid sloshing,and the numerical results were compared with analytical solution.The results show that,by ABAQUS numerical simulation with high precision,this work illuminates the availability and reliability of the proposed method,which provides a new analysis method for the study of dynamic analysis of 3D liquid sloshing.Finally,the author analyzed the shaking frequency and liquid depth,width of the relationship of such systems with different liquid height to width ratios considered.
