Experimental and theoretical modeling of cargo sloshing during braking
- The outputs from a simplified mathematical designed to simulate the liquid cargo-vehicle interaction during an emergency braking maneuver, have been compared with full scale data regarding the sloshing pressure on one of the vehicle chambers. While the specific dimensions and fill level of the fluid within the chamber in the full scale testing, have been considered for the simulation model, the vehicle has been simplified to a straight truck instead of an articulated truck. Nevertheless, the pressure within the chamber is realistically modelled, concerning the maximum and minimum pressures attained, with differences lower than 10% between the simulation and the experimental data. Consequently, these results suggest that the articulation pertaining to the articulated vehicle, does not affect in a significant manner the maximum and minimum values of the pressure within the chamber. A nonlinear model for the suspension, however, could improve the model performance.

On the other hand, simulation results suggest that the effect of sloshing could cause a loss of braking efficiency on the order of 7%, when such performance is measured in terms of the stopping time.…
