| Abstract: | A new method for calculating frequency response function is derived by extending the Series Expansion Method(SEM) which was proposed by auther, recently. The new method is more accurate than SEM and can be used for free free systems. Numerical examples demonstrate that the new method is efficient. |
| Keywords: | structural dynamic analysis frequency response function modal truncation modal acceleration series expansion method |
