    For the analysis of car interior noise at high speed, the influence of autobody aerodynamics should be taken into account, besides the vibration and acoustic radiation of powertrain, the random excitation from road and the vibration inputs of tires, and so on. A model of CFD was built. And the most turbulent area of autobody surfaces was located. The spectrum of average aerodynamic pressure of monitoring points on front door window was also obtained by unsteady calculation. So, the more accurate analysis of car interior noise can be processed due to loading the power inputs listed above to the simulation model, which is looked as the foundation of further optimization of car interior noise control.
