| Abstract: | A concept of global frequency response function(GFRF) has been presented.The MIMO modal parameter identification modal has been established,based on the weighting sum of modal shape squares.The analytical results of artificial example show that the proposed method has the advantages of accuracy,consistency,separating closely-spaced modes and eliminating random noise.This method can be used for experimental modal analysis of large or complicated structure. |
