摘要：

The equations of vibrations of a stringer-reinforced spherical sandwich shell under unsteady loading are obtained. In analyzing the elements of the elastic structure, the models of the Timoshenko theory of shells and rods are used. The numerical method for solving the obtained equations is based on the application of the integro-interpolation method for constructing finite-difference schemes for equations with discontinuous coefficients. The problem of the dynamic behavior of a spherical sandwich shell under unsteady loading is solved taking into account the discreteness of the ribs. Numerical results are plotted and analyzed.
