Research on Aerodynamic Noise of Base Styling Characteristics of Car Rearview Cover

Abstract:

The 3-D digital models are established for two kinds of base styling of rearview cover. The compare analysis using Fluent model is based on the acoustic theory of computation. The results show that the average sound pressure level of up-raised rearview cover model is about 5 dB lower than that down-raised rearview cover model, and in all of the frequency range were apparently different. At the same time, the vortex of down-raised happened at the back location, which is more closer to the passenger’s ear, and affect the car interior noise. The results of analysis will conduct the design of rearview styling effectively.
