| Abstract: | The suspension transfer path was analyzed based on LMS OPAX method. The force acoustictransfer function was obtained using the principle of reciprocity method and low volume sound source.Based on the OPAX calculation, the reliability of OPAX algorithm was tested and verified. The schemewas proposed based on CAE analysis, and the roar problem was finally solved. |
