Abstract: When the aircraft performs the maneuver flight, the whole structure is in a large overload condition, and the problem of the fluid-structure interaction of the fuel tank sloshing is complicated. Based on a certain type of aircraft fuel tank, a fluid-structure interaction simulation method is proposed with ABAQUS and Star-CCM+ software. By investigating the fluid-structure interaction effect of the fuel tank sloshing during the Split-S maneuver, the morphological change of fuel, the pressure of the fluid filed and the time-history curves of the stress of tank components are obtained. The influence of the filling rate changes on tank sloshing is analyzed. The results indicate that the influence of the overload on the stress and strain of tank components is greater than that of the liquid sloshing, and the stress of all components increase with the increase of filling rate except the upper skin.
