| Abstract: | The analysis of eigenvalue and eigenvector sensitivities with respect to design parame ters is very important in the structural dynamic design. It is quite meaningful to reduce calculation work within a given accuracy. In this paper, a new method is derived for the analysis of a class of free structures such as submarine and torpedo by using power series expansion. This method has high accuracy and the accuracy can be adjusted according to requirement. A numerical example of a free-free beam with two rigid modes is given to il lustrate the effectiveness of the pressent method. |
