✦ Synopsis

This paper deals with the practical engineering problem of cantilever plates with rigid point supports. A highly accurate, experimental procedure is outlined for the transverse free vibration analysis of these plates. The modal properties of these plates are obtained from the experimental data. In this analysis, a frequency domain mathematical model is used along with frequency response function (FRF) measurements obtained from the plate. These measurements are made using an FFT based spectrum analyzer. Numerical results are compared with theoretically predicted values to show the excellent agreement between the two sets of data. Experimental and theoretical mode shapes and contour plots are also provided for a large number of plate aspect ratios and point support locations. Excellent agreement is also observed here.
