| Popis: | The problem of transporting swaying cargoes on the vessels in the conditions of rough waters. To study the motion of the cargoes and forecast the emergency it is offered to use the vibratory displacement (transportation) theory mainly developed by the native scientists. The motion of a flat solid body along the vibrating rough surface is considered to be the model. The use of the model enables one to define the velocity of the slow motion of the body and its direction to the symmetry plane of the vessel or to its boards. The last case is related to the center-of-gravity shift of the vessel, which leads to an increased roll, or even capsizing. The critical roll angle is specified—the angle corresponding to the start and motion of the swaying cargo on board of the vessel. The possibility of using deformable or granular materials has been noted. |
