In order to ensure the transportation safety of tankers,this paper studies the impact characteristics of the liquid in the tank during the braking process.The standard model was used to conduct numerical simulation analysis of the sloshing impact process of the liquid in the tanker body.The analysis indicates that the filling rate,filling medium and the external excitation have the most significant effect on liquid sloshing in the tank.The numerical simulation of the above three main influencing factors is carried out respectively.The results show that the impact force of liquid sloshing decreases with the increase of the filling rate.As the density of the filling medium increases,the sloshing impact force increases,and the viscosity of the filling medium has negligible effect on the sloshing impact force.With the increase of external excitation,the liquid sloshes violently;the time for the sloshing impact to peak is then advanced,and the sloshing impact force also increases.Finally,the validity of the simulation model is verified by scaling experiment.This study sheds light on how to ensure the safe operation of the hazardous chemical tankers.
