Experimental Investigations on Free Vibration of Plates
Author: H. R. Kemparaju
Publisher:
ISBN:
Category : Fracture mechanics
Languages : en
Pages : 15
Book Description
In this article, the natural frequencies, damping ratios, and damping constants of plates in different materials such as Steel, Aluminum, and Copper, with different boundary conditions like clamped-clamped-clamped-clamped (CCCC), clamped-clamped-clamped-free (CCCF), clamped-clamped-free-free (CCFF), clamped-free-free-free (CFFF) and free-free-free-free (FFFF), have been experimentally investigated. Natural frequencies obtained experimentally are compared to the natural frequencies obtained from numerical analysis using finite element analysis package ANSYS. The effects of different parameters like density, boundary conditions, and fixed edge length on free vibration characteristics of the plates are discussed. The damping ratios are determined experimentally, and the effect of boundary conditions on the damping ratio is also discussed.

Natural Frequencies and Mode Shapes of Plates with Interior Cut-Outs. X

Pages : 94
Book Description
The effect of square holes on the natural frequencies and mode shapes of a 7 in. x 10 in. clamped rectangular plate were investigated. The frequencies of the first five modes were obtained in separate experiments using holographic interferometry and accelerometers and analytically using the finite element method. The shapes were observed in the holography experiment and photographs were taken. For a plate without holes, the experimental frequencies were approximately 10% lower than the theoretical values possible due to some rotation of the plate edges. Using a 25 element model, the finite element program gave frequencies within 1% of the theoretical values. For central square holes, the frequencies of each mode varied with hole size in a number of ways. A correlation between the variation of frequencies and mode shapes was noted.
