Vibrations of Systems with Geometric Symmetry. Quasi-symmetrical Systemsgeometric symmetry find wide application in many areas of engineering. They form various kinds of machine platforms, cyclically repeated forms of stators, rotors with blades mounted on them, etc. Symmetric systems are widely applied also in the civil engineering where their use is convenient due to

Vibrations of Regular Ribbed Cylindrical Shells forces and the deformations of the middle surface of the shell proposed by V.V. Novozhilov and L.I. Balabukh are used. The main advantage of these equations is that in them Betty’s law is observed very precisely and thus the dynamic stiffness matrix is symmetric, and therefore it is possible t
