There was a need to validate the longitudinal performance required for the cargo securement, as current standards exhibit differences.
A model has been proposed in this paper, to simulate the effect of a shifting cargo on the braking efficiency of the vehicle. Results suggest that the braking efficiency can be greater in the case of a shifting cargo, as a result of the uncoupling of the cargo-vehicle systems, implying that similar braking forces are exerted on a reduced mass. The shifting of the cargo can occur as a result of the vibration of the vehicle, that leads to having a diminished friction force to prevent the shifting of the cargo.
Longitudinal Load transfer light sensitivity to cargo type, fill level and the impact distance.
Maximum sloshing effect for the case of the lowest fill level 12
while for half fill level the sloshing cargo performs as a dynamic damper, with a maximum effect of 6 in the case of medium impact input
The sloshing effect for the highest fill level yielded a mixed output, with the maximum impact distance producing a positive but moderate effect.
