Vibration analysis of a thick ring interacting with the disk treated as an elastic foundation

In this study the in plane flexural vibration of a thick ring interacting with Winkler foundation is analysed on the basis of the analytical and numerical method. The effect of rotary inertia and shear deformation is included. The normal frequencies and natural mode shapes of the system vibration are determined. Achieved results are discussed and compared with an experimental data. FE models are formulated by using ANSYS code.
