| Abstract: | Based on the theories of differential equation and matrix analysis, the transfer matrix for analysing free vibration of structures is expressed by an exact form other than power series and numerical integration ones and therefore numerical calculations can be carried out with higher precision and higher efficiency, comparing with the transfer matrix methods used before. By using the close and exact form, an example of free vibration of circular cylindrical shell with variable thickness is presented in the papre. |
