Dynamic behavior of the large amplitude lateral sloshing is analytically studied in partially filled elliptical tankers. Theory of elliptical trammel pendulums is employed for modeling of the large oscillation of the fluid inside the elliptical container. Nonlinear governing equation of the motion is derived employing the Hamilton principle. Standard and modified Energy Balance Method (EBM) is adopted as the solution technique. Natural frequencies of the free oscillation are analytically obtained as a function of the initial amplitude. It is proved that the nonlinear dynamical system can behave mutually as a hardening and softening system based on the tanker aspect ratio. A number of numerical simulations are carried out and accuracy of the obtained analytical solution is evaluated.

“…Higher frequencies in lateral direction showed importance and complexity of consideration of slosh force and its interaction with vehicle dynamics in roll plane as induced in steer maneuvers. In the majority of fluidvehicle coupled sloshing analysis, quasistatic approach [3][4][5][6] or mechanical analogy method has been applied [7][8][9][10] to calculate fluid slosh forces and moments.…”

The directional response and roll stability characteristics of a partly filled tractor semi-trailer vehicle, with cylindricaltank, are investigated in various maneuvers. The dynamic interaction of liquid cargo with the tractor semi-trailervehicle is also evaluated by integrating a dynamic slosh model of the partly filled tank with five-degrees-of-freedom ofa tractor semi-trailer tank model. The dynamic fluid slosh within the tank is modeled using three-dimensional Navier-Stokes equations, coupled with volume-of-fluid equations and analysed using the FLUENT software. The coupledtank-vehicle model is subsequently analysed to determine the roll stability characteristics for different maneuvers. Theresults showed the interaction of fluid slosh with vehicle's dynamic. Another findings of this investigation also revealed that the roll stability of a tractor semi-trailer tank carrying liquid was highly affected by fluid sloshing and caused degradation of roll stability in comparison with vehicle carrying rigid cargo.
