Abstract
The paper presents the study by finite element analysis and by two experimental methods of the vibrations of a cantilever beam. The beam is made of homogenous material and has constant cross-section. The fundamental period of flexural vibrations is first calculated from analytical relation. The beam is modelled in CATIA and by Finite element analysis, the first ten frequencies of vibrations are obtained. The numerical and theoretical results are in good agreement. The experimental tests were performed via two methods: first, the oscillatory motion is video-recorded and the image is processed to obtain the period of vibration; second, a small acceleration sensor is attached to the free end of the beam and it provides a signal with the same period as the vibration of the system.
