摘　　要：基于波动理论,探讨了阻振质量对典型船体连接结构中振动波传递的阻抑特性。兼顾基座阻振质量布置工艺,开展了阻振质量偏心距对其隔振特性的影响研究。从工程应用的角度出发,将阻振质量带引入动力舱段基座结构的刚性隔振设计中,联合应用声固耦合法和统计能量法数值研究了阻振质量截面尺寸、截面形状参数和布置位置对舱段全频段隔振特性的影响规律。在此基础上,开发了动力舱段基座阻振质量隔振效果工程快速预报方法,旨在为艇体早期结构声学设计提供参考。Based on wave theory,the characteristics of wave propagation of typical hull structure from blocking mass are discussed.Concerned with assemble process,the influence of eccentricity of blocking mass to its vibration isolation performance is analyzed.From the engineering application point of view,the blocking mass ribbon is introduced into rigid vibration design of typical base structure.Combining the acoustic-structural coupled method and Statistical Energy Analysis,the full-band influences of blocking mass ribbon cross-section size,cross-section shape parameters and layout location to base isolation performance are discussed.On this base,the quick-engineering prediction method of base blocking mass ribbon in power cabin is developed,which aims to provide reference for primary acoustic design of typical hull structure.
