Abstract

In this paper, the general framework for dynamic substructuring is extended to time-variant interfaces among connecting substructures. Specifically, a time-variant interface due to a sliding contact is considered. The contact can be without or with friction. The problem can be tackled in time domain using primal assembly and numerical time integration, and in time-frequency domain using dual assembly, thus obtaining a Time Dependent Frequency Response Function (TD-FRF) of the assembled structure. The method is applied to lumped parameter models of substructures, and, under some assumptions, it can be extended to simple finite element models.
