Abstract: Many of 2D mechanical models have been devel-oped to simulate liquid sloshing of a partially filled tank with different shapes. However, those models didn’t represent properly the complex liquid motion, especially in the case of portable tanks. Indeed, forces exerted on the liquid can be lat-eral, longitudinal and vertical. Then, liquid displacement and pressure forces applied to the tank walls are undervalued and may cause design flaws. In this case, 2D mechanical models are ineffective for liquid motion simulation. In previous studies, a 3D equivalent mechanical model has been developed. This dy-namical model is used to simulate different liquid motion in a partially filled tank that consider any sort of excitement forces and get more accurate results in terms of displacements and pressure forces. In this study, a brief description of the new dy-namical model is given, including the liquid discretization pro-cess, stiffness and damping coefficients computing method and equations of motion. Afterward, the model is applied to an el-liptical cross section tank to obtain displacement and pressure forces of the liquid. Finally, the results are compared to the lit-erature.
