| Abstract: | Presents the analysis of the natural vibration of the cylindrical mast in ship adopting the assumptions of both the membrane stress and the unvariability of the transverse section and using the synthetic discrete method. A numerical example is added in illustration of the proposed method. Some results of the calculation are given.It is concluded that the synthetic discrete method is a better method which can not only reduce highly the number of the unknown independent variables, but also keep on enough accuracy. |
