摘要探讨了圆盘型进气消声器对蜗壳振动和声辐射的影响。 - 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。 - When other sound sources are under further control , the air inlet may become the primary sound source . under this situation it is proposed to apply good intake mufflers . usually the intake muffler needs to combine with the air cleaner in an integrated design to meet requirements of air admission and cleaning as well as perform an effective control over the air inlet noise
而当其它声源得到进一步控制后，进气噪声有可能成为主要声源，这时需考虑采用性能良好的进气消声器，通常进气消声器要和空气滤清器结合，进行一体化设计，既能满足进气和滤清方面的要求，又可使进气噪声得到有效的控制。 - This paper has presented the situation of intake silencer research and application and expounded the intake noise engendering cause and the basic theory on controlling the intake noise . then a research established in the accurate determination of resonance frequencies of different kind of helmholtz resonators is done . according to different assumptions , four kind of mathematical models are established , and the relations between them are discussed
