Research was carried out into the role of the small concentrated mass of frequencies and forms regarding free bending vibrations of circular cylindrical shell. The quantitative result, which was obtained by the method of final element, are compared with the well-known theoretical and experimental data. It has been established, that the effect of declining the least of split own frequencies depends heavily on the geometric and wave parameters of the shell. The limit of applicability of a well-known formula to assess the lowest frequencies of spectrum has been examined. It has been shown that the interaction of bending and radial vibrations must be taken into account already in linear functions. © 2017 The Authors.
