Vehicle intake system acoustic modality simulation and test
XIA Yunfeng;YANG Erwei;TIAN Guannan;CHERY Automobile Co. ,Ltd.;
As to the issue that there is a great effect of the noise of automobile intake system on the whole automobile NVH performance,the feasibility of simulation method and test method on straight pipe acoustic modality is verified. The CAE simulation is performed on the acoustic modality of intake system,and a series of tests are designed to investigate the reasons that there is a gap between CAE simulation and test. The position of muffler component of intake system is suggested by the acoustic modality analysis results of an example.
