Note : to reduce noise , install an engine intake filter and use a suitable expansion muffler 注:為減少噪聲,請安裝進汽過濾器和適當的消音器。
With the development of vehicle noise control technology , engine intake noise con - trol has become the emphasis 隨著汽車噪聲控制技術的發展,進氣噪聲已成為汽車噪聲控制的重點。
With its pull - back motor , big engine intake , flame details and huge tires , off road power ' s name says it all 它的回力功能,超強力引擎,火力能量和巨型輪胎都說明了我們叫她越野車也不為過。
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 在此基礎上設計并加工了兩類七個共振型進氣消聲器,研制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件,并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。
Other content in this paper is the design and investigation of spiral inlet port . the geometries that compose intake port have been repeatedly when intake port scheme was designed . the intake port scheme has been carried out steady - flow test . the experiment data has been analyzed and investigated , then the performance of inlet port has been estimated by the fluid coefficient and the whirl ratio . at last , the spiral inlet port scheme has been selected based on matching relation of the factors of combustion system . in addition , how to " intake port synthesis performance coefficienf ' evaluate engine intake port has been discussed 本文的另一項內容是螺旋進氣道的設計和研究。通過對進氣道的幾個主要結構參數進行反復修改擬定進氣道方案,并對其進行穩流試驗,分析和研究試驗數據,利用流通系數、渦流比進行進氣道性能評估,根據燃燒系統要素的匹配關系,確定了兩種螺旋進氣道方案。另外,本文探討了“進氣道綜合性能系數”對發動機渦流進氣道性能的評估能力。
