| Abstract: | The structural vibration and noise of a vehicle cab structures have been systematically simulated. Modal analysis is made to obtain the structural modal parameters, the finite element modal is checked and verified by the test result and the dynamic response is calculated based on the reliable finite element model. The acoustics characteristic of the inner acoustic field is used for analysis. The noise obtained within the driver cabin is distributed,some conclusions were drawn which were useful for noise reduction in low frequency for the vehicle. |
| Keywords: | cab finite element noise modal sensitivity |
