Abstract�� 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.
Keywords�� tank truck   volume of fluid (VOF) method   liquid sloshing   two phase flow
