| Abstract: | On the basis of the complex modal theory in modal analysis, the identification method for a vibtation system is presented. The least square method is used to fit the transfer function of the vibfation system in frequency domain and the structure modal parameters are identified using a microcomputer. It is shown that only the transfer fuuction is used without the need for any other information. The initial parameters are calculated on computer. |
