resonant silencer meaning in Chinese

共振消音器

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。
