This paper deals with some important theoretical problems concerning experimental modal analysis. Several admittance parameters are first introduced, in terms of which an expansion series of residual admittance is developed. Then, the transformation equations relating physical parameters with admittance parameters and those relating complex modal parameters with real ones are determined. Finally, an explanation is given about the application of the expansion series of residual admittance for the reduction of the degrees of freedom in modal synthesis.(Author abstract)
