摘要：
In this paper, the optimization design of vibro-acoustic behavior of non-uniform stiffened cylindrical shells is realized. On the restrain conditions of weight, minimum radial quadratic velocity is considered 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 arrangement of ring-stiffened cylindrical shell is better than the traditional ring-stiffened cylindrical shell.
