摘　　要：分析主船体振动与噪声源对上层建筑传播的影响因素,进行结构的优化设计。在主船体与上层建筑之间设置弹性隔振器,利用隔振器支承上层建筑并与主船体形成隔离层阻断振动与噪声向上传播,通过PATRAN有限元计算软件,建立仿真模型计算隔振器支座处结构强度,得出优化的结果。实船测量表明,上层建筑的振动及噪声得到有效改善,对比传统的减振降噪技术,弹性上层建筑技术为高速船提供了轻量化的方案。The factors affecting the propagation of vibration and noise from main hull to superstructure was analyze to optimize the design of structure.The elastic isolation mount was set between main hull and superstructure,which forms isolation layer and prevent propagation of vibration and noise.A simulation model was established to calculate the structural strength at the support of the elastic isolation mount in PATRAN software,and the optimized results were obtained.The measurement of the actual ship showed that the vibration and noise of the superstructure are improved effectively;compared with the traditional vibration and noise reduction technology,the elastic superstructure technology provides a lightweight scheme for the high-speed craft.
