ABSTRACT
ABSTRACT: The directional dynamics of a partly-filled B-train road tanker is investigated in the presence of transient fluid slosh. A computationally efficient transient fluid slosh model, assuming incompressible and irrotational flows, is developed and integrated with a multi-body dynamics model of a B-train car with 78 Degrees of Freedom. The effects of transient slosh responses on directional performances of a tanker-train combination are also evaluated under different steering maneuvers and filling conditions. The results showed that the directional performances of the partlyfilled vehicle combinations in the presence of transient free-surface motion could be efficiently evaluated using the proposed fluid slosh model.
