Research on Dynamic Characteristics of Lateral Sloshing in Liquid Tank Semi-trailer

In order to ensure the safety of liquid tanker transportation and aiming at the liquid sloshing of the lateral movement of the semi-trailer tanker. The VOF(Volume of Fluid) multi-phase flow model and the standard k-epsilon turbulence model are used to numerically simulate the shaking process of liquid in the tank. The simulation results show that different lateral acceleration, the number of baffles, different liquid filling ratio can pose different forces and moments on the tank. Thus affecting the driving stability of the tanker. When the liquid filling ratio is fixed the greater the lateral acceleration, the greater the amplitude of the liquid sloshing, the greater the impact on the tank. With the increase of liquid filling ratio, the peak value of the impact on the tank decreases and gradually becomes steady over time. Within one cycle, the more baffles the smaller peak value of the lateral force impact on the tank and the less the number of impacts, the faster the rate of lateral force decay. The results show that the research method in this paper is feasible and provides a design reference for improving the lateral stability of liquid tank truck.
