汽车消声器多工况综合性能的评价方法（Evaluation Method of Vehicle Muffler's Comprehensive Performance under Multiple Working Conditions）
汽车 消声器 多工况
2009/5/22
定义了一种对消声器多工况下加权插入损失、背压系数、线性度系数进行综合量化的评价函数，以反映消声器在各个主要工况下的消声效果、空气动力性能以及声品质特征。以GT-Power软件为工具，计算了3种不同消声器的评价函数，并与实验结果进行对比。结果表明，该评价方法可以很好地反映消声器在多个工况下的综合性能，为消声器的匹配设计提供依据。
