| Abstract: | Based on the generalized mode theory of linear vibrating defective systems, an identification method of generalized modal parameters is presented in this paper. By use of the method, which combining the direct method with iteration method in frequency dominion, all the generalized modal parameters can be ideatified without any initial value. It is shown that the present method is effective and useful. |
