| Abstract: | This paper deals with some important theoratical problems concrning experimental modal analysis. Several admittance parameters were first introduced, in terms of which an expansion series of residual admittance was developed. Then, the transformation equations relating physical parameters with admittance parameters and those relating complex modal parameters with real ones were determined. Finally, an explanation was given about the application of the expansion series of residual admittance in reduction of degrees of freedom in modal synthesis. |
