| 中文摘要: |
| 针对某车型进气系统谐振腔没发挥作用这一实际问题，对进气系统进行声学模态试验与CAE仿真分析，掌握了进气系统声腔模态特性，找出了问题根源，并优化了进气系统的谐振腔位置，消除了进气系统引起的车内轰鸣问题。 |
| 英文摘要: |
| Acoustic mode of vehicle intake system was validated by test and CAE simulation, to find out the reason that a resonator in system did not work. The booming noise was removed by changing the position of the resonator which was optimized according to the results of the acoustic mode analysis. |
