“…Therefore, the liquid in the model absorber need only have the same density as the liquid in the prototype and a viscosity low enough to give a Reynolds number of greater than 10. This conclusion is in close agreement with observations given by Popov et al [18] for liquid sloshing in horizontal cylindrical road containers. Popov et al showed viscosity had no e!ect for Re in the range 10}10, and the e!ect was small for Re in the range 10}10.…”

“…Tank trucks are frequently subjected to steering and braking-induced accelerations, while carrying partially filled liquid tanks. The resulting fluid movements within the tank yield additional forces and moments imposed on the vehicle, which affect the braking performance and roll stability limits of the vehicle in an adverse manner [1][2][3]. On the basis of the reported highway accidents involving heavy vehicles, it has been suggested that tank trucks are 4.8 times more * likely to be involved in rollover accidents than the rigid cargo vehicles [4].…”

“…A few studies have investigated the dynamic fluid slosh within cylindrical and rectangular containers subject to acceleration fields in either roll or pitch planes [3,7,8]. These studies have derived forces and moments caused by fluid slosh under either a lateral or longitudinal acceleration, whereas only a single study has attempted to study the lateral dynamics of a partlyfilled tank truck subject to lateral force and roll moment due to dynamic fluid slosh [9].…”

The directional dynamic analyses of partly-filled tank vehicles have been limited to quasi-static fluid motion due to computational complexities associated with dynamic fluid slosh analyses. The dynamic fluid slosh causes significantly higher magnitudes of slosh forces and moments in the transient state that cannot be characterized through quasi-static approach, which provides reasonably good estimates of the mean responses. In this study, a three-dimensional nonlinear model of a partly-filled cylindrical tank with and without baffles is developed to investigate the significance of resulting destabilizing forces and moments caused by the transient fluid slosh, and the effects of baffles. The baffles and the end caps are modeled with curved shapes. The analyses are performed under varying magnitudes of steady lateral, longitudinal and combinations of lateral and longitudinal accelerations of the tank, and two different fill volumes using the FLUENT software. The results of the study are presented in terms of mean and peak slosh forces and moments, and variations in the mass moments of inertia of the fluid cargo within a clean bore and a baffled tank, for two different fill volumes and different magnitudes of acceleration excitations. The ratios of transient responses to the mean responses, termed as amplification factors, are further described to emphasize the significance of dynamic fluid slosh on the forces and moments induced on the vehicle. The results in general suggest that the mean responses attained from dynamic fluid slosh analyses correlate well with those attained from the quasi-static analyses for a clean bore tank. The amplification ratios of the resulting forces and moments could approach as high as 2. The results clearly show that the presence of baffles helps to suppress the peak as well as mean slosh forces and moments significantly.

Tank vehicles have quite poor roll stability in driving. Therefore, the purpose of this article is to investigate tankers' roll stability by vehicle dynamic modeling. As a fluid-solid coupling multi-body system, tank vehicle's dynamic modeling must take liquid sloshing into account. The conventional solution on liquid sloshing by hydrodynamics is difficult and time-consuming, and the modeling of tankers obtained by this method was a distributed parameter system with infinite degree of freedoms. It was quite difficult and complicated to analyze tankers' dynamic features and to design active control system by the distributed parameter system. Therefore, three different methods to describe liquid sloshing effects in partially filled tanks with elliptical cross sections were proposed in this article, which are the estimation of liquid sloshing, the improved estimation of liquid sloshing, and the modeling of equivalent mechanical model for liquid sloshing. Then, the dynamic modeling of tank vehicles was commenced based on that. It was found out that the roll stability performance of tank vehicles obtained by different models differs with each other. The quasi-static model obtained by the estimation of liquid sloshing could get an estimation on tanker's rollover threshold quickly and easily, but it is with poor accuracy. The improved quasi-static model obtianed by the improved estimation of liquid sloshing could give a more accurate result on tanker's rollover threshold, the solution is also easily and quickly. Rollover analysis based on equivalent mechanical model of liquid sloshing could reflect vehicle's dynamics and is with high accuracy, but the process is of great complexity.
