| 7. | To achieve this , the rear exhaust silencer has been located in a transverse position where it also serves as an aerodynamic diffuser , but still allows sufficient space for the storage of a spare wheel
要做到这一点,后方排气消声一直设在横向位置,也可作为气动扩,但仍留有足够的空间储存了备胎 |
| 8. | 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。 |
