| Abstract: |
| Objective To study the sloshing law of fuel in automobile fuel tank and provides reference and basis for structural reliability design of automobile fuel tank and stable supply of automobile fuel. Methods The geometric model of a certain type of automobile fuel tank was established. The VOF (volume of fluid) method was used for numerical simulation. The control variable method was used to compare and analyze the effects of different baffles, different impact acceleration and different filling ratio on the fuel sloshing and the pressure on the wall of the fuel tank. Results In the case of no baffle and large impact acceleration, the fuel sloshing was more intense, the suction pipe had instantaneous suction phenomenon, which lead to the instability of fuel supply and the greater pressure on the fuel tank, affecting the structural reliability of the fuel tank. In the case of small filling ratio, because of the fuel sloshing, the suction pipe was prone to instantaneous suction, which lead to the difficulty of fuel supply. Conclusion The use of partition, small shock acceleration and large filling ratio in the automobile fuel tank are beneficial to prevent the suction pipe from being sucked out instantaneously, thus ensuring the stable supply of fuel. However, the pressure on the tank wall will increase if the filling ratio is too large. Therefore, a reasonable filling ratio should be maintained. |
