Abstract

In recent years, the structural dynamic community showed a renewed interest in dynamic substructuring (i.e.component coupling) techniques, especially in an experimental context. In this paper the reverse problem is addressed: the decoupling (or identification) of a substructure from an assembled system. This problem arises when substructures cannot be measured separately but only when coupled to neighboring substructures, a situation regularly encountered in practice. In this work we present a so-called dual approach to substructure (dis)assembly This dual framework allows imposing different equilibrium and compatibility conditions during decoupling in a transparent and straightforward manner. By varying these conditions, four substructure decoupling techniques will be derived in a unified way. Thereafter, the decoupling techniques will be applied to a real decoupling problem using measured data.
