| Abstract: | With the totally enclosed masts of non truss structure for ships as the study object, numerical analysis of the natural frequencies and modes of the vibration of the masts are carried out using 3 D finite element method. Meaningful results of the vibration behavior of the masts with such complicated structure are obtained. |
