Analyse des gekoppelten Systems Reifen-Hohlraum-Rad-Radführung im Rollzustand und Entwicklung eines Rollgeräuschmodells

The complex state of rolling of the tire-cavity-wheel-suspension system is experimentally investigated. The influence of the contact of the tire with a rough road surface and the tire's vibrational excitation are analysed in experiments. The findings gained are used to build up an improved rolling noise model. Beyond the structural dynamics of the tire, the model includes the tire-cavity medium plus the wheel and simulates the interaction with the modeled suspension.
