摘要
本文介绍了300 t级高速巡逻艇的减振降噪设计,应用基于统计能量分析方法的VAONE软件对舱室噪声进行预报,根据预报结果采取减振降噪改进措施,并通过实船噪声测量,验证了设计效果。
The design for reducing vibration and noise levels of a 300 t high-speed patrol is presented. The cabin noise levels are frstly predicted by using the software VAONE based on the statistical energy analysis method. Then the vibration and noise control solutions are determined from the numerical predication and analysis. Finally the shipboard noise is measured during a trial and the measured noise levels onboard meet the relative requirements.
