Abstract

The vibrational power flow in a spatially periodic supported beam excited by a force at any position is studied. In non-propagating bands, the driving force does not do work and there is no power flowing from the source into the beam. In propagating bands, the driving force does work and the power supplied by the source is transmitted into the beam. No matter where the beam is excited, one half of power flowing from the source travels along the beam in the positive direction and the other half in the negative direction. For different propagating bands, the power flowing from the source can be reduced to the minimum by suitably adjusting the excitation location.
