Tire-pavement-interaction
Multi-physical and multi-scale theoretical-numerical modelling of the tire-pavement-interaction
Research topics
Vertical displacements at tread cross section
- Development of a general understanding of the complex interactions of coupled vehicle-tire-pavement system
- Efficient and reliable structural analysis and prediction of the thermo-mechanical behaviour of the tire-pavement-system to obtain deeper knowledge on the short term dynamical processes inside the pavement at single overruns by steady state rolling
Application of the Arbitrary Lagrangian Eulerian method to simulate tire-pavement-interaction
- Obtaining deeper knowledge on the short term dynamical processes inside the pavement at single overruns by steady state rolling as well as on the thermo-mechanical and inelastic structural bahavior of tires at varying loads, velocities and driving manoevres
- Deduction of parameters for an improved durability and less susceptibility to damage of pavement structures
- Improved understanding of processes inside the pavement structure in consequence of multiple overruns under consideration of varying pavement temperature due to climatic impact
