S.P. Tymoshenko of the National Academy of Sciences of Ukraine popup.description2 Research report: 30.p., 8 fig., 23 sources Based on the linear model SP Tymoshenko, the stress-strain state of a closed multilayer orthotropic ribbed conical shell under dynamic loading is investigated. The asymmetrical arrangement of the shell layers, the attached masses and the elastic base are taken into account. The solutions of the problems are obtained by the method of decomposition by the forms of natural oscillations of shell structures using the Duhamel integral. The analysis of numerical solutions of problems of oscillations of asymmetric three-layer cylindrical shells of rotation at axisymmetric non-stationary loads is carried out. The influence of asymmetry of three-layer cylindrical shells on their dynamic behavior is investigated by means of the finite element method and the natural frequencies of their oscillations are determined, which gives the possibility of rational choice of three-layer structure.
