Abstract: To investigate the evaluating accuracy of Quasi-static (QS) method and the analysis correctness of tank vehicle rollover stability, the relationship between the actual transient liquid sloshing effects in partially-filled oval tanks and the QS evaluating results are studied. Then, the impact of transient liquid sloshing on vehicle rollover stability is investigated by analyzing the balance between the rollover moment caused by the movement of the center of gravity of liquid bulk and the aligning torque caused by the load transfer between tires of the two sides. Finally, the key points that influence the intensity of transient liquid sloshing and the optimal tank shapes are discussed based on the rollover stability analysis results of tank vehicles with different oval tanks.

Key words: automobile engineering, tank vehicles, Quasi-static method, roll stability, transient liquid sloshing, FLUENT simulation
