Description
Summary:The transverse vibration of a beam excited axially by a harmonic motion transmitted through intermittent elastic contact is experimentally studied. The beam’s configuration is clamped–(clamped–guided). It is shown that said transverse vibration can be considered essentially as the fundamental transverse mode of the beam and can occur when the frequency of the excitation is four or six times the frequency of said mode. The energy transfer between the excitation source and the beam occurs only when the beam is in certain spatial configurations. This constitutes an argumental phenomenon. Experimental results are given and compared with models.
