Review of the Theoretical Investigation of Slamming of Global Wave Loads on Ship Structures
摘要
Abstract
The global wave loads slammed on ship structures is a strong nonlinear problem of fluid struc⁃ture interaction. It usually results in major vibration of the hull girder according to the 2-node resonant fre⁃quency in waves, which is called whipping. Two kinds of structural problems are caused by whipping: the ultimate strength problem and the fatigue damage problem, both of which are unavoidable in the design of ship structures. In this paper, theoretical investigation of the problem presented above is reviewed systemi⁃cally, and both advantages and disadvantages of two- and three-dimensional theories in the prediction of the slamming force are presented. The review shows that certain basic assumptions and mathematical mod⁃els in the two-dimensional theory may pose restrictions on the wide application of the two-dimensional the⁃ory in hypertrophy vessels, multi-body vessels, and ocean platforms, though it has been used for more than half century. However, the three-dimensional theory bypass those restrictions and can be used more widely in naval architectures and ocean engineering. The three-dimensional hydro-elasticity theory includes some nonlinear effects such as the flare influence and can be used to predict the slamming with a higher accura⁃cy. This is one of the most important developing direction of the theoretical investigation for the slamming of global wave loads on ship structures.关键词
