Finite Element Analysis And Experimental Study Of Ice Force On Inclined Structure

The inclined structures are popular in defeating ice encounter. Many efforts have been made in the last twenty years to further study the interaction of sea ice with the various types of the inclined offshore structures. In this paper, the combination of the nonlinear contact patterns using finite element and ice model tests will be used to analyze the ice force on inclined structure.The paper studies the mechanic characters of ice at first and discusses several mechanism models and the formula calculation in profession criterion of ice load on the inclined structure. According to the finite element and nonlinear contact theory, using the ANSYS, a mathematical pattern of ice-incline interaction can be created. The efferts of the principal parameters which include the friction coefficient, slope angle, ice strength and ice thickness act on the inclined structures were discussed. At the same time, the ice model tests are carried out. They come to the same results, which prove the theories in this paper are correct.The combination of theory and experiment give the basis of choosing the ice force patterns in sea ice design criterion. It is very useful in practical ice load calculation.
