Dynamic Response Analysis on Train Liquid Storage Tanks under Impulsive Excitation

Abstract

Take the typical train liquid storage tank as research object, the vibration modes and the fluid-solid coupling dynamic responses of the tank are analyzed under the impulsive excitation using finite element software ANSYS. The research indicates that the difference of the liquid volume in tank has great influence to the structural stress and strain. With the increasing of the liquid volume, the tank natural frequencies gradually reduced, so the liquid sloshing have great effect on the structural vibration modes. And if the tank is full of the liquid, the stress and total deformation of the tank can be obviously reduced.
