声学典型分析理论及内燃机电站低噪声控制统计能量分析法模型

有限元分析法、边界元分析法及几何声学分析法在内燃机电站的低噪声计算中已经得到应用，但存在局限性。介绍了声学分析计算的基本理论，并建立了基于统计能量分析（SEA）法的内燃机电站低噪声分析模型，指出了SEA是低噪声电站振动与噪声分析的新方法。

Acoustic Classic Theory and Model of Low-Noise Control Based on SEA for Power Plant with Internal Combustion Engines

Now the methods such as finite clement analysis, boundary element analysis and geometry acoustics analysis had been used in low-noise analysis of power plant with internal combustion engines, but there was limitation. It introduced acoustic theory and established basic calculation-model based on the statistieal energy analysis of power plant with internal combustion engines. It pointed out that statistical energy analysis would be a new analysis calculation-tool of low-noise power plant with internal combustion engines in the field of sound and vibration.
