声学声学材料阻尼性能的弯曲共振测试方法 - Shanghai gepai wood limited is professional in acoustic materials to the design , development , production and sales
上海格湃木业有限公司专业致力于声学材料的设计、研发、生产与销售。 - It is well known that the coupled interactions between the ship hull and the surrounding fluid field of explosion give rise great influence to both the fluid loadings over the structural wetted surface and the responses of the hull . jt is the coupling effect that provides the major difficulties in the underwater explosion induced dynamic responses of the ship structure . the second order doubly asymptotic approximation method ( dda2 ) has been commonly employed in the world to deal with the coupling effect
本文针对daa方法不适合于分析敷有声阻抗与水差不多的声学材料(如玻璃钢与消声瓦)的船体结构与水下冲击波相互作用的局限性，依据声波的反射和透射原理对二阶daa方法的高频段进行了改进，发展并提出了能够分析声学材料流固相互作用的adaa方法( acousticdaa ) ，拓展了应用范围，使现有的二阶daa方法成为它的一个特例。
