【摘要】 本文基于变频调速技术挖掘了其在船舶机械系统减振降噪方面的潜力。首先,将变频调速技术作用于常见的船舶机械系统,设计了变频调速方案;其次,基于宽带平稳随机过程,构建了船舶噪声信号模型,并对变频调速技术作用于船舶机械系统的减振效果进行了仿真分析。结果表明,变频调速技术应用于船舶动力机械系统具有20%～30%的减振性能,后期可继续进行变频调速系统多参数变化对减振影响规律的探究,进一步优化减振性能,为变频调速技术更好地落地解决船舶机械系统的振动与噪声提供理论基础。更多还原

【Abstract】 Based on variable frequency speed regulation technology,this paper explores its potential in vibration and noise reduction of ship mechanical system.Firstly,the frequency conversion speed regulation technology is applied to the common ship mechanical system,and the frequency conversion speed regulation scheme is designed.Secondly,based on the broadband stationary random process,the model of ship noise signal is constructed,and the vibration reduction effect of variable frequency speed regulation technology on ship mechanical system is simulated and analyzed.The results show that the application of variable frequency speed regulation technology in marine power machinery system has 20%～30% vibration reduction performance.In the later stage,the influence of multi-parameter changes of variable frequency speed regulation system on vibration reduction can be further explored,and vibration reduction performance can be further optimized,which provides a theoretical basis for the better landing of variable frequency speed regulation technology to solve the vibration and noise of marine mechanical system.更多还原
