摘要
船用柴油机的振动噪声水平对船舶的舒适性有着重要影响,振动噪声指标已和功率密度、尺寸重量等性能指标一起,成为衡量船用柴油机性能的重要指标。从声源识别技术、进排气噪声控制设计技术、低噪声设计预报技术、有源消声技术等方面入手,介绍了船用柴油机振动噪声控制技术的研究现状;并提出了未来振动噪声控制技术研究方向和发展趋势。可为相关技术研究、产品开发、系统设计分析提供指导。
The vibration and noise level of marine diesels has big influence on the comfort property ot ships, which has been the important index of engine performance as well as power density, volume and weight and so on. The development of identification and separation of noise source, the intake and ex- haust noise control technique, the modern prediction method of low noise and new findings of noise con- trol method are presented. Moreover, the status and development trend of noise control technology of in- ternal combustion engines is proposed, which provides reference for technology investigations, product development and system design.
