| Abstract: | The problem of obtaining free vibration frequencies and mode shapes of rectangular plates resting on combinations of classical
(i.e., clamped, simply supported, or free) edge supports is one that has been investigated for more than one hundred years.
More recently, the superposition method has been developed for obtaining accurate analytical-type solutions for this family
of problems. The object of this paper is to report on the results of numerous experimental tests carefully performed in order
to verify the superposition method and associated computer software. Experimental and computed results are compared for a
wide range of plate configurations. Very good agreement between theory and experiment has been obtained with regard to both
plate natural frequencies and mode shapes. It is concluded that this computational procedure constitutes a powerful new tool
for analysis of rectangular plate vibration problems. |
