Abstract

In the work, the dynamic properties of shell and its filling acoustic medium as the connected elastic-acoustic system are investigated. Computation model is elaborated on the base of the finite element method. The oscillation spectrum of partial and connected of systems is determined and compared in the range to 50 Hz. It is established that only region of the lowest frequencies of the behavior of the connected system is similar to partial.
