Abstract

Abstract

Based on the smooth particle hydrodynamics (SPH) method, the stability of the tank truck and the mitigating effects of different baffles were studied. Firstly, the liquid sloshing pressure in a rectangular container was simulated with results in agreement with experimental ones, to validate the effectiveness and accuracy of the SPH model. Secondly, a 2D elliptic tank truck model was established, which was filled with 93# gasoline. The impact pressure on the tank wall and the trajectory of the liquid barycenter were analyzed under different horizontal sinusoidal excitations and roll excitations. The results show that, the liquid sloshing is violent with no mitigating baffle, and the mitigating effects of the baffle will be influenced by the forms of external excitations. When the angle between the normal direction of the mitigating baffle and the inflow is small, the stability of the tank truck will be improved.
