解釋
發電機消聲器-
The silencer greatly reduces noise level emitted from engine inside the cabin, creating a quiet and tranquil environment
特強的音量滅聲器大大減低由機器發出的噪音,締造寧靜的環境。 -
Engine operating with fuel system, water pump, lubricating oil pump, aircleaner and exhaust silencer ; not included are battery charging alternator, fanand optional driven components
發動機帶燃油系統、水泵、機油泵、空氣濾清器和消聲器運行,而不包括為蓄電池充電的發電機、風扇和其它選件。 -
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。 -
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共振腔的共振頻率,從而為正確設計出針對發動機進氣噪聲頻率特性的helmholtz共振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。
