Investigations of motion of the lifeboat lowered from ship's deck

摘要

A calculation model as well as differential equations of motion of the lifeboat lowered from the deck of the ship under rolling in rough seas, are presented. The equations were numerically integrated. The computer software elaborated on their basis makes it possible to trace instantaneous positions of the lowered lifeboat, calculate velocities and accelerations of its elements, as well as determine forces acting on the boat and persons accommodated in it.
