THE EFFECT OF TIP REMOVAL ON THE NATURAL VIBRATIONS OF UNIFORM CANTILEVERED TRIANGULAR PLATES

Abstract

Experimental results are obtained for the lowest 6 natural frequencies and the associated nodal lines of trapezoidal plates of uniform thickness clamped on one edge. Three series of plates are investigated. Each series consists of 6 plates and is developed from a triangular plate by progressively cutting off portions of its tip parallel to its clamped edge, giving a clipped wing effect. Two of the series originate from triangular plates of delta wing plan form with aspect ratios of 2 and 4. A triangular plate with a mean chordline sweepback angle of 45 is used as the basis for the third series. Results are presented in form of graphs, tables, and photographs. A method of treating plates of nonisotropic material is described. The use of interpolation to extend the results to a broader field of plate shapes is also discussed.
