Analysis of the car body sound-structure interaction and the contribution of plate based on LMS Virtual Lab
Based on a passenger car model for the analysis of objects, this paper analyses the acoustic sensitivity of this car body model by the application of the Acoustic model of LMS Virtual Lab software and in turn analyses the contribution of plate, the analysis process uses the installation position of the left front shock absorber for the vibration source , acquire the distributed cloud chart and the acoustic transfer function of driver both ears , according to the cloud chart distribution condition of the internal sound field in certain frequency can be seen ,according to the transfer function curve the frequency relative to the sensitivity peak value can be seen, the plate witch contribution is maximum can be found by analyzing the contribution of plate, these provide the guidance for the following structures design.
