摘　　要：近年来,随着我国汽车保有量的急剧上升,汽车噪声已经成为城市噪声污染的主要来源之一,直接影响居民的身心健康,汽车噪声污染问题亟待解决。汽车噪声源中,进气噪声因气体流体动力学特性极其复杂,因而没有固定的降噪措施。针对这个难题,设计了一种集空气滤清器和消音器一体的错列复合阻抗式消音器,可以同时实现除尘和降噪两种功能,而且不会在周期性进气脉冲噪声的激励下产生额外的共振噪声。In recent years,with the sharp increase in the number of automobile in China,automotive noise is become one of the main sources of urban noise pollution,directly affecting the physical and mental health of residents.The problem of automotive noise pollution urgently needs to be solved.Among the sources of automotive noise,intake noise is extremely complex due to the gas fluid dynamics characteristics,so there is no fixed noise reduction measure.In order to solve this problem,a kind of staggered composite impedance silencer is designed,which integrates air filter and Silencer.It can achieve both dust removal and noise reduction functions without generating additional resonance noise under the excitation of periodic intake pulse noise.
