COMPUTER PROGRAMS FOR PLATE VIBRATION INCLUDING THE EFFECTS OF CLAMPED AND ROTATIONAL BOUNDARIES AND CYLINDRICAL CURVATURE-OPTION 2

A comparative study is made of various methods for computing the free vibration modes and natural frequencies of thin plates with clamped and rotational supports and cylindrical curvature. The methods include closed form analytical, digital computer, nomographic, and graphical computations. Based on the results, preferred methods of computation are recommended. These methods-Option 2 are of particular value in extending previously formulated digital computer programs for obtaining the vibroacoustic response to turbulence excitation of a plate. Computer results for a particular case provide a comparison of the effect of clamped-clamped and simply supported boundaries on the vibratory response of a plate subject to turbulence excitation.
