Abstract

Results from a theoretical and experimental comparison study of the vibration of a cantilever beam are presented. A verified theory was used for the theoretical prediction and real time and time average holographic interferometry was used for the experimental verifications. The first 16 vibration modes were predicted and measured for each cantilever beam, and a detailed comparison is presented. Reasonably good quantitative agreement was obtained for both natural resonant frequencies and mode shapes.
