| Research Abstract |
The calculation program considering the coupling effect of ore particle motion and the ship structure deformation utilizing DEM and FEM is developed.The behavior of actual ore particle is able to reproduce by introducing the critical rotation moment in DEM. The static ore pressure is able to calculate accurately by utilizing DEM. It is necessary to consider the effects of tightening and condensing of ore particles under cyclic rolling motion in order to evaluate the ore pressure accurately. The deformation of hull structure affects on the ore pressure at certain level.
