Mode vibrations of plates – experimental analysis

Mode vibrations of plates - experimental analyses. In this paper results of the square MDF plate and circular saw blades examination with the use of the harmonic method to static identification of resonant frequencies and shapes of mode vibrations are presented. Obtained results reveled that for circular saws with large holes in a saw blade appeared two resonant frequencies for the same nodal number. Keywords: harmonic method, resonant frequencies, circular saw blades.
