摘　　要：文章对非均匀圆柱壳振动及声辐射性能进行优化设计。研究过程中,在保证重量基本相同的约束条件下,以径向均方速度为目标变量,得到肋距及肋骨尺寸最佳组合。结果表明:非均匀圆柱壳优化后的振动及声辐射特性优于均布环肋圆柱壳。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.
