| 中文摘要 | 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。; An evaluation function of muffler was defined to describe the weighted insert loss,exhaust back pressure coefficient and linearity coefficient in a comprehensive quantitative way,so as to analyze sound reduction effect,aerodynamic performance,as well as sound quality characteristics of the muffler in multiple working conditions.The evaluating functions of three different mufflers were computed by simulation with GT-Power and experiment tests.The comparison shows that the evaluation method could describe the comprehensive property of a muffler under multiple conditions,which could be used in muffler's matching design.; 国家“863”高技术研究发展计划资助项目(2006AA110105) |
