Abstract

Hybrid testing of a cantilever beam with two controlled degrees of freedom at the interface between virtual and physical structures is performed in this work. To circumvent instabilities caused by delays in the transfer system and inaccuracies caused by error in the characterization of the transfer system, an alternative open-loop method based on harmonic balance method is adopted that is suitable for steady-state motion. The periodic solution that ensures synchronous motion of the interface between the virtual and the physical structure is found via quasi-Newton iterations. Results show a strong agreement between the two sides of the interface, thus proving the capabilities of the method in dealing with continuous structures with two controlled degrees of freedom.
