This paper presents the development and solution of the differential equations of flexural vibrations of a system of n elastically connected concentric rings. By using these equations, the particular case of a two-ring system is analyzed in detail. The frequency equation and displacement functions are then presented. The analysis includes a consideration of the effect of rotatory inertia. Vibration experiments were made on physical model of the two-ring system. The results are compared with results of calculations based on the theory. An interesting phenomenon encountered during the investigation suggests the possibility of exciting, at a definite frequency, patterns of displacement that probably represent the combination of two normal modes.
