Abstract
At SAIC-GM-Wuling (SGMW) the greenhouse wind noise performance of their vehicles
has gained a lot of attention in the development process. In order to evaluate
and improve the noise quality of a newly developed SUV a digital simulation
based process has been employed during the early stage of the design. CFD
simulation was used for obtaining the flow induced exterior noise sources.
Performance metrics for the quality were based on interior noise levels which
were calculated from the exterior sources using a SEA approach for the noise
transmission through the glass panels and propagation to the driver’s or
passenger’s head space. Detailed analysis of the CFD results allowed to identify
noise sources and related flow structures. Based on this analysis, design
modifications were then applied and tested in a sequential iterative process. As
a result an improvement of more than 2 dB in overall sound pressure level could
be achieved.
