Note : to reduce noise , install an engine intake filter and use a suitable expansion muffler 注:为减少噪声,请安装进汽过滤器和适当的消音器。
With the development of vehicle noise control technology , engine intake noise con - trol has become the emphasis 随着汽车噪声控制技术的发展,进气噪声已成为汽车噪声控制的重点。
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,超强力引擎,火力能量和巨型轮胎都说明了我们叫她越野车也不为过。
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 在此基础上设计并加工了两类七个共振型进气消声器,研制了发动机进排气消声器性能测试实验台,开发了发动机进排气消声器声学性能测试软件,并在该实验台上测试了所设计的进气消声器静态工况下的传声损失,从实验的角度研究了共振腔的尺寸、形状对其共振频率的影响及其趋势。
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 一维轴向传播理论能够准确预测共振腔的共振频率,从而为正确设计出针对发动机进气噪声频率特性的helmholtz共振型进气消声器提供依据,达到有效控制发动机进气噪声的目的。
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 本文的另一项内容是螺旋进气道的设计和研究。通过对进气道的几个主要结构参数进行反复修改拟定进气道方案,并对其进行稳流试验,分析和研究试验数据,利用流通系数、涡流比进行进气道性能评估,根据燃烧系统要素的匹配关系,确定了两种螺旋进气道方案。另外,本文探讨了“进气道综合性能系数”对发动机涡流进气道性能的评估能力。
