  1. In order to carry out the acoustic and aerodynamics performances tests, seven resonators are designed and made, and a specialized engine intake silencer and exhaust silencers test bench was designed. the tests and analysis are performed as well. on the basis of the intake noise spectrum of sc7080a, a three - parallel - connected resonant silencer is designed, and that has efficiently controlled the acceleration noise of sc7080a

    在此基礎上設並加工了兩類七個型進氣消聲器,研製了發動機進排氣消聲器性能測試實驗臺,開發了發動機進排氣消聲器聲學性能測試軟體,並在該實驗臺上測試了所設的進氣消聲器靜態工況下的傳聲損失,從實驗的角度研究了的尺寸、形狀對其的影響及其趨勢。
  2. The research and the application shows that the resonator geometrical parameter has effect on its resonant frequency, and the one dimension ( 1 - d ) model can predict the frequency accurately. therefore, if an engine intake noise spectrum is known, one can design a helmholtz resonant silencer to control the intake noise

    一維軸向傳播理論能夠準確預測,從而為正確設出針對發動機進氣噪聲特性的helmholtz型進氣消聲器提供依據,達到有效控制發動機進氣噪聲的目的。
