Abstract
The alternative indirect methods to estimate interfacial force and moment are first given as theoretically exact methods which are derived from the equation of motion. How to directly acquire the F/Q (dynamic stiffness)-type frequency response functions and the blocked boundaries to apply are described in detail. As applications of interfacial force and moment, dissipated power exactly estimated by the total power or energy flows into a system and exactness of the transfer path analysis for structure-borne sound are described. Using a finite element model of a plate-beam structure, computational verifications are given for the equalities.
