基于预报的客滚船振动和噪声控制措施分析

Forecast-based analysis of vibration and noise control measures for Ro-Ro passenger ship

客滚船的舒适性与乘客的体验直接相关,控制作为舒适性重要衡量指标的振动和噪声,是客滚船设计的重中之重。该文以某型客滚船为例,介绍了基于经验和数据库的振动和噪声早期预报以及振动和噪声的数值预报,同时基于上述预报的建议和结论采取相应的振动和噪声控制措施。通过试航实测结果,验证了预报和控制措施的有效性,为今后客滚船在设计和建造过程中振动和噪声控制提供了可借鉴的经验。

The comfort of a ROPAX is directly related to the passengers’experience,so that controlling vibration and noise as an important measure of comfort is a top priority in the design of a ROPAX.Taking a certain type of ROPAX as an example,this paper introduces the early prediction and the numerical forecast of vibration and noise based on experience and database,and accordingly proposes corresponding vibration and noise control measures based on the suggestions and conclusions of mentioned forecast.Based on the actual measurement results of the sea trial,the effectiveness of forecasting and control measures is verified,which shall provide a referential experience for the vibration and noise control of ROPAXs in the design and construction process in the future.
