Abstract: | Natural frequencies of a two layered elastic ring, on equi-spaced, identical radial supports, are obtained by using a wave approach. Two types of support conditions are investigated. With the outer layer viscoelastic, the theory of forced damped normal modes is used to obtain the resonant frequencies and the modal loss factors of the structure. Results presented show the effect of the thickness ratio on the resonant frequency and the modal loss factor. The effect of rotational constraints at the supports is also reported. |
