  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

    在此基礎上設計並加工了兩類七個共振型進氣消聲器，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計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共振腔的尺寸、形狀對其共振頻率的影響及其趨勢。
