Lateral load transfer due to sloshing cargo in partially filled containers

  • A testing methodology has been proposed in this paper, to compare the load transfer derived from solid and liquid cargoes when the carrying vehicle is subjected to a lateral acceleration in a tilt table. Besides the type of cargo, the other factors (a) One-quarter fill level (b) One-half fill level (c) Three-quarter fill level (d) Fast input considered are the fill level and the rate at which the considered are the fill level and the rate at which the acceleration input is acceleration input is exerted on the vehicleexerted on the vehicle. The acceleration The acceleration input can represent the entering of the carrying vehicle into a input can represent the entering of the carrying vehicle into a curved portion curved portion of of aa road. The testing device integrates the needed components to measure the fourmeasure the four--wheel loads of the wheel loads of the carrying vehicle, while carrying vehicle, while providing different times to attain providing different times toA testing methodology has been proposed in this paper, to compare the load transfer derived from solid and liquid cargoes when the carrying vehicle is subjected to a lateral acceleration in a tilt table.

The performance measure selected is significant to assess the rollover trend of a vehicle, on the basis of the wheel loads at both sides of the vehicle. both sides of the vehicle. The outputs from the experiments suggest that the sloshing suggest that the sloshing cargo transfercargo transferss the greater loads, the greater loads, regardless of the fill level and regardless of the fill level and acceleration rate inputacceleration rate input, as a result , as a result of the shifting of the center of of the shifting of the center of gravitygravity of the liquidof the liquid, and of of the the dynamic vibration at the end of dynamic vibration at the end of the perturbation input. In this respect, while the solid cargo the perturbation input. In this respect, while the solid cargo exhibits an initial peak and decay, the exhibits an initial peak and decay, the sloshing cargo exhibits sloshing cargo exhibits several oscillations of the saseveral oscillations of the same magnitude, which is attributed me magnitude, which is attributed to the to the liquid inertia and liquid inertia and to the to the reflection of the surface waves. reflection of the surface waves.
