Abstract: A simulation platform is developed for analysis of directional dynamics of partly filled tank vehicle combinations by integrating a steady-state fluid slosh model of the partly filled tank to TruckSim software. A modified Reuleux-triangle tank cross-section with a curved bottom is further proposed to achieve reduction in mass centre height and to adapt to current designs of saddle mounts. The coupled tank-vehicle simulation platform is used to evaluate roll dynamic performance of a six-axle tractor-semitrailer combination with the proposed tank cross-section considering different cargo fill volumes. The roll performances, evaluated in terms of steady rollover threshold, lateral load transfer and peak directional responses, are further compared with those of currently used tank cross-sections. The comparisons suggested that the modified Reuleux-triangle tank can yield improved roll performance. Furthermore, the coupled tank-vehicle simulation platform could serve as an effective virtual design and simulation tool for parametric design of partly filled tank trucks.
