Abstract

The problem of oscillations of the systems containing pipelines filled with the liquid is one of the actual problems of modern techniques. It is important to estimate the parameters of vibrations and acoustical fields of such objects in order to provide the construction from damaging, but calculation of these complicated systems demands major computing resources. Therefore the consideration of simple model problems which have exact analytical solution is actual. On these models it is possible to analytically explore main effects and also to use them as the test problems for computing packages. The problem of joint oscillations of infinite thin cylindrical shell with ideal acoustical fluid inside it is considered. The propagating waves and energy flux are analyzed in the system shell-liquid. The comparison of dierent mechanisms of energy transmission in the shell and input of the energy flux in the water is fulfilled
