【 摘 要 】

In this paper, we use the finite element software MSC•PATRAN and MSC•NASTRAN to establish the FEM model. Then we analyze the racking condition strength under the conditions of inclined shipping, and discuss the stress of the hull structure, the distribution of the hot spot and the deformation of the deflection under the flexible design concept. Some general conclusions under the design concept are obtained, which will be expected to contribute to the development of the design concept of the whole ship flexible structure.
