Wyznaczenie obciążeń na poszycie okrętu wywołanych uderzeniem fal i uderzeniem w lód i ich wpływ na bezpieczeństwo okrętu
Abstract
The main problem is the vessels rather accurate determination of the hydrodynamic loads so-called hydroelasticity outside . This can be done by theoretical analysis , computer simulation or by experiment. This gives the hydrodynamic pressure distribution on the walls of the ship's hull and also on the walls of marine vessels .The most dangerous are the impact of extreme storm waves , the impact of the wharf and the impact zone of the ice. Additional load causes the wind. The article presents a general formula for the force of waves acting on the surface of the hull. Ripple makes finding the bottom of the vessel and cause a stroke at the bottom. Extreme pressure on the bottom surface is determined by the formula 2 . In the event of an impact on the ice should be determined reduced mass of the vessel was imported to the point of impact (formulas 8 and 9). Knowing the maximum acceleration (formula 10 ) may designate the impact force . Knowing the pressure distribution of aggregated load can be determined by extreme stress and deformation of the structure of the ship , which determine the safety of navigation of the unit.
