The radial natural vibrations of the threelayered cylindrical shell are considered. Kirchhoff-Love`s hypotheses are accepted for the thin isotropic bearing layers. The work of the inplane shear, compression over thickness and variations in displacements are taken linear along the transverse coordinate for the thick filler the conditions of displacement continuity are not used on the contact boundaries. The deformations are small. The investigation of variations in natural frequencies of a cylindrical shell as dependent on the wave parameter is given as an example.
