Reviewing this project, Dr. vehicles Blumrich appreciates the project delivery The decision to upgrade theand ways of cooperation. It was aeroacoustic wind tunnel reflects theimpressive, Dr. Blumrich says. Despite current trend of vehicle electrification.the short deadline, Siemens managed to The absence of a loud combustiondeploy everything in time. In addition, engine in hybrid and electrical vehicles,Siemens offered additional cooperation besides the tire-road noise, makes theprojects for further enhancements of aeroacoustic noise sources much morethe system after the installation. We audible. Because of the relativehave a common understanding to start decrease of powertrain noise, thejoint research projects in this respect. tire-road noise and aeroacoustic noiseThat was another reason why we increases in relevance. Dr. Blumrichselected Siemens as a partner.says. And it increases the need for aeroacoustic measurements. If youFKFS has further developed its toolbox remove the noise sources likefor optimizing the interior noise by combustion powertrain or side mirrors,focusing on the unsteady aeroacoustics, human hearing will start to focus onwheel rotation, and ground simulation other noise sources, which means that itfor a correct underbody flow with becomes important to investigate andrespect to the upcoming trend of optimize other parts. autonomous vehicles. n29'
