Numerical Study on the Distributions of the Ice Pressure Area and Structural Response for Ship Maneuvering in Level Ice

摘要

In this paper, the structural response of a simple stiffened panel when a ship advances in a level ice is simulated. Author has developed the numerical simulation to predict the continuous distributions of the ice force and the ice pressure area along the waterline for ship maneuver in level ice. In this simulation, the motion of the ship is described by the rigid body simulation of the surge, heave and pitch motions. It is shown that the ice force distribution around the waterline and the local ice pressure area are strongly influenced by the motion of the ship. The calculated pressure area is used in the FE simulations of a simple stiffened panel as a force boundary condition. The relationship between the ice pressure area and the structural response is discussed.
