Experimental study of the argumental transverse vibration of a beam excited through intermittent elastic contact by a harmonic axial motion

Abstract

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 this vibration is in the fundamental transverse mode of the beam, and can occur when the frequency of the excitation is four or six times the frequency of the fundamental transverse 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 to models.
