The dispersion curves are given, the resonance frequencies are found. The stress distribution in a construction is investigated. In case of low-frequency vibrations the engineering formula for approximate calculation of the construction is offered. The graph of dependence of a relative accuracy on frequency is given.enBox-like shellplatevibrationsdispersion curveresonanceArticle
