| Abstract: | Describe the working principle of the marine stern roll and study the form of working loads on it and the method for structural strength calculation with Finite Element Method(FEM).With the calculation of some traditional one for example,an analysis of their stress distribution characteristics and the limitations of carrying capacity is made.Then a concept of the large stern roll which can effectively increase their loads is proposed.And the structure strength reliability of an improved stern roll and its v... |
