Bevor ein Auto vom Band rollt, testen die Hersteller die Fahrzeug-Designs virtuell. Besonders schwierig ist die Simulation der Reifen, weil sie beim Fahren durch Schlaglöcher und über Bodenwellen extrem beansprucht werden. Mit der Reifenmodellierungs-Software »CDTire« bieten Fraunhofer-Forscher ein Simulationswerkzeug an, das Räder realitätsnah darstellt und die Automobilindustrie in zahlreichen Analyseszenarien unterstützt. Wie die neue Software außerdem hilft, Kosten zu sparen und aufwändige Testfahrten von der Versuchsstrecke in den Fahrzeugsimulator zu verlegen, erklären Dr. Manfred Bäcker und Dr.-Ing. Christoph Burkhart vom Fraunhofer-Institut für Techno- und Wirtschaftsmathematik ITWM.
Warum stellt die Simulation von Reifen eine so große Herausforderung dar?
