Long description:

Der Tagungsband zur ATZlive-Veranstaltung ?Automotive Acoustics Conference 2023? befasst sich mit technischer Akustik und NVH, welche zu den wichtigsten Indikatoren fu?r Fahrzeugqualita?t und -verarbeitung geho?ren. Mit den grundlegenden Vera?nderungen der Antriebstechnik ru?cken diese Aspekte daher zunehmend in den Fokus der Automobilforschung und -entwicklung. Fahrzeugarchitekturen, Antriebssysteme und Designgrundsa?tze werden aufgrund der weltweiten Emissionsgesetzgebungen, die energieeffiziente Fahrzeuge fo?rdern, einer kritischen Betrachtung unterzogen. Schon in sehr naher Zukunft muss die gleiche oder eine ho?here NVH-Performance durch Leichtbaustrukturen, kleinere Motoren mit Turbolader oder alternative Antriebsstra?nge erreicht werden. Die internationale Automotive Acoustics Conference bietet hierfu?r ein wichtiges globales Forum fu?r den Wissens- und Meinungsaustausch.

Inhalte: NVH-Methoden fu?r den Antriebsstrang, Reifen-/Stra
