摘　　要：对柴油机的辐射噪声水平进行预估,分析柴油机性能对整机辐射噪声的影响,是进行柴油机低噪声设计的重要技术途径。以某型船用大功率高速柴油机为研究对象,阐述了柴油机结构噪声预估方法,分析了柴油机在不同运行工况下的整机辐射噪声,研究成果可应用于船用柴油机的振动噪声控制。To evaluate the radiated noise level and to analyze the influence of diesel engine performance on its overall radiated noise are important technical approaches for low noise diesel engine design. This paper takes a high power marine high speed diesel engine as the example to elaborate the evaluation method of diesel engine structural noise and analyzes its overall radiated noise under different working conditions.
