Abstract

Experiments on a flexible-beam impact oscillator are described in which the spatial structure of typical motions is explored. The beam is held in a fixed mount with clamped-free boundary conditions, and an electromagnetic shaker is used to force a sinusoidally-vibrating impactor to strike the free end of the beam. Bifurcation diagrams using frequency as the bifurcation parameter are obtained using a computer-driven data acquisition system. It is shown that over 90% of the mean square response amplitude is captured by the first proper orthogonal mode for the cases examined.
