Computational simulation of nonlinear liquid sloshing in a tank truck

Abstract

Liquid sloshing in the tank of a tank truck is one of the important factors affecting the driving stability of the tank truck. When the external motivation is larger, the liquid sloshing phenomenon shows the nonlinear characteristics of the movement, causing rollover accidents. Therefore, it is of practical significance to study the movement of a tank car to improve its stability. Based on the equivalent pendulum mechanical model under nonlinear condition, the liquid sloshing nonlinear motion of a tank was investigated. A simulated liquid sloshing test bench was used to verify the validity of the nonlinear model. This study provides a theoretical basis to improve the driving stability of a tank truck.
