摘要

Structural model test method is used to predict the ultimate strength of aSWATH (small waterplane area twin hull) ship in this paper. Similaritytheory, combined with finite element method, is applied to conduct thestructural model design in the ultimate strength test. MSC.Nastran isapplied to analyze the FE-models of the SWATH ship and its scalemodel to ensure the consistency of the stress value and stressdistribution of the FE-models. External load in the structural model testmostly simulates transverse wave loading on the SWATH ship. At last,numerical simulation of ultimate strength for the test model is executedbased on MSC.Marc nonlinear FEA.
