Abstract
In this paper, we study the possibility that impact force, which is called "pulsating force", might suppress nonlinear vibrations arised on Duffing system. Our experimental equipment described by Duffing's equation is a buckled steel elastic cantilevered beam on a periodically moving support. This equipment has a hammer in order to add the pulsating force to the beam. The displacement of free end of the beam is measured by a laser displacement sensor. The paper show that the pulsating force suppresses the large-amplitude vibration arised on our experimental setup. We hope that the pulsating force will control nonlinear vibrations arised on flexible structures.
