On the Estimation Method of Slamming Pressure for Ship Structural Analysis in Combination of CFD with Heuristic Method

摘要

In order to estimate the stress distribution due to slamming of aship, it is necessary to determine the local pressure distributionaccurately. CFD is a promising approach for this purpose,however, a large amount of computational effort is required if a3-dimensional calculation is adopted. In the present paper, thepressure distribution is estimated by means of a 2-dimensionalCFD approach and is modified with the aid of a heuristicmethod to take account of the 3-dimensional effect in slammingphenomenon of the ship with forward speed in waves. Theproposed calculation method of pressure distribution isexamined by conducting the structural analysis of the ship andthe calculated stress distribution is discussed from the practicalpoint of view.
