The Study of Tanker Semi-trailer's Steering Stability on the Fluid-Structure Interaction

Under sharp turn condition, side tumbling of tanker semi-trailer often happens. Aiming at dangerous accidents of this kind, in this paper, the ALE (Arbitrary Lagrange-Euler) method is employed to analyze the process of tanker semi-trailer during sharp turn. Under different liquid filling ratio, liquid sloshing influence on the steering stability is analyzed. Obtained the Y-direction force of some units located at middle of tank's left side, the Y-direction acceleration and the Z-direction displacement of the key nodes at the right side of the tank. The results were significance for tanker semi-trailer's steering stability simulation.
