摘　　要：将约束优化理论引入声学设计领域,以带结构的水下隔声层为分析对象,阐述了序列二次规划算法用于声学优化设计的基本过程和关键步骤。通过对带结构的水下隔声层所用橡胶材料参数的优化设计,为水下隔声橡胶的参数设计提供了设计的基本方向,对于提高其水下隔声性能具有重要意义。By introducing the theory of constraint-optimizing into the field of acoustic design, model for sound insulation of underwater structure which contained honeycomb shape is analyzed. Basic process and key process are stated by of SQP for optimizing the acoustic design are deseribed. By optimizing the rubber coating properties, basic guidance about parameters devised for underwater sound-insulation rubber are provided, and which have important significance in improving the performance of the underwater sound insulation.
