Abstract
In this paper a hybrid numerical-experimental approach for dynamic testing, the so called realtime dynamic substructuring (RTDS) is exploited for nonlinear system testing. To this end, the RTDS approach is combined with control based continuation (CBC), a method recently gaining much popularity in the nonlinear system identification community. A slim cantilever beam is used as a numerical example system in this study. The displacement of a certain degree of freedom of the beam is transferred in realtime to a real damper element with friction by an electrodynamic shaker. The force generated by the damper is fed back into the model for the calculation of the displacement at the next time step. The CBC involves a stabilizing external control loop, which allows the nonlinear force-displacement characteristic of the system to be determined experimentally.
