| Abstract: | The problem of simplification of boundary conditions in ships' local structure vibration analysis is studied. Based on the analysis of different results from various methods, a new method of simplification and modification of boundary conditions is proposed.The numerical result shows that the method can describe the real boundary conditions more exactly and is simple and reliable in engineering analysis. |
