Abstract
In this contribution, Frequency Based Substructuring is applied to a
well-known benchmark structure with special attention to correct
modelling of the interface problem. Various approaches with the Virtual
Point Transformation are used to incorporate the effect of interface
flexibility that is present in the clamped connections. An extension of
the rigid displacement basis with flexible interface displacement modes
is proposed and evaluated. Furthermore, a practical approach using a
Transmission Simulator is used in order to improve the quality of the
interface description.
