Abstract

An approximate evaluation of natural frequencies is described for a lower oscillation spectrum range of a thin elastic finite-length cylindrical shell with two attached cantilever elastic plates. The plates are attached to the shell along a section of generatrix. The described problem is solved in the contact statement with satisfaction of compatibility conditions for the shell and the plates according to the Bubnov method. Some examples are considered.
