Abstract
A simple model of blade interactions through an elastic disk is suggested in this paper. The elasticity of a disk is modeled using a ring on an elastic foundation. The linear discrete model of a bladed disk is obtained using the flexibility matrix. The asymptotic procedure is used to analyze the localization of vibration eigenmodes and to obtain eigenfrequencies. The eigenfrequencies loci veering phenomena are treated. The results of the asymptotic analysis are compared with the data of the direct numerical simulations.
