Abstract

AbstractUsing the system of equations corresponding to the classical theory of orthotropic cylindrical shells, the free vibrations of thin elastic orthotropic cantilever cylindrical panel are investigated. In order to calculate the natural frequencies and to identify the respective natural modes, the generalized Kantorovich-Vlasov method of reduction to ordinary differential equations is used. Dispersion equations for finding the natural frequencies of possible types of vibrations are derived. An asymptotic relation between the dispersion equations of the problem at hand and the analogous problem for a cantilever rectangular plate is established. A relation between the dispersion equations of the problem and the boundary-value problem of a semi-infinite orthotropic cantilever cylindrical panel is derived. As an example, the values of dimensionless characteristics of natural frequencies are derived for an orthotropic cantilever cylindrical panel.KeywordsBoundary vibrationsEigenfrequenciesCylindrical panel
