  • The liquid sloshing in braking process of tank truck was simulated by volume of fluid (VOF) model. The forces and their locations of a single room and weight distribution of a truck were calculated. The reliability of the calculation method was validated by comparing with experimental results. The results show that the maximum of Fx (force in direction x), Fy(force in direction y) and C (The ratio of weight acting on the front axle and rear axle) increase as the deceleration increases without a baffle. When the liquid filling ratio increases, the maximum of Fx increases firstly and decreases afterwards, the maximum of Fy increase, and C increases in the starting and ending period of braking process and decreases during the period around 1 s. When there is a baffle, as the area of the baffle becomes bigger, the maximum of Fx, Fy and C decreases.
