Multiple Regression Analysis of Gasoline Engine Combustion Noise

  • 摘要: 为了更合理地评估发动机燃烧噪声,将燃烧噪声按传递路径不同分为直接燃烧噪声和间接燃烧噪声。基于两种燃烧噪声的传递函数不随发动机工况变化而变化,在每个频率下建立缸压、缸压引起的转矩力与燃烧噪声之间多元回归模型并求解回归系数,得到相应频率下的直接燃烧噪声和间接燃烧的传递系数。对25 Hz~20 000 Hz频率范围内两种燃烧噪声传递函数进行了计算和分析,结果表明:在各个中心频率下的多元回归模型拟合度较高,说明应用此方法获取的直接和间接燃烧噪声传递系数比较准确;直接燃烧噪声和间接燃烧噪声的传递函数在2 000 Hz左右频率段均存在峰值;该汽油机在25 Hz~1 250 Hz频率范围内,间接燃烧噪声高于直接燃烧噪声,在1 250 Hz~20 000 Hz频率范围内,直接燃烧噪声高于间接燃烧噪声。
