AB - Numerical analysis of fluid sloshing in tank wagons is one of the updated matters focused by railway engineers. The free surface of fluid becomes unstable and turns into a dynamic complex non-linear problem for fluid-structure interaction (FSI). In this paper, first, the dynamic response of the tank, including lateral force analysis and pressure distribution during braking, is obtained using an explicit dynamic finite element model based on the Multi Material Arbitrary Lagrangian Eulerian method (MM-ALE); then, the simplified model is developed for sloshing during turning. Numerical finite element model is validated using a test setup data. Comparing these models during turning with parametric studies for tank filling, it is observed that frequency and sloshing amplitude, when filling is less than 25%, have less than 10% of difference; therefore, the simplified model in the above conditions can be used with an acceptable accuracy because of a remarkable reduction in the time and cost of numerical calculations.
