The Dynamic Response Analysis on Train Liquid Storage Tanks under Harmonic Excitation

Abstract

This paper take the typical train liquid storage tank as research object, the fluid-solid coupling dynamic responses of the tank are analyzed under the track irregularities 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. When the tank is not filled with liquid, the liquid has large-scale amplitude sloshing, and the stress and strain are much bigger than the static condition. But if the tank is full of the liquid, the stress and total amount of deformity of the tank can be obviously reduced.
