Experimental Investigations on Free Vibration of Plates

CODEN: JTEVAB

Abstract

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.
