@@@@In this paper, the optimization design of vibro-acoustic behavior of non-uniform stiffened cylin-drical shells is realized. On the restrain conditions of weight, minimum radial quadratic velocity is consid-ered as the objective, optimal combination of frame spacing and type of the ring-stiffened is studied with the given total length and radius. The results show that the vibro-acoustic behavior of the non-uniform arrange-ment of ring-stiffened cylindrical shell is better than the traditional ring-stiffened cylindrical shell.
