Description

Tire-soil interaction models define the forces, stresses and movement
at the boundary between tire and soil. This work assessed the
real-time capabilities of these models. Material and method: i)
Code the models using MATLAB/Simulink; ii) Combine a full
car with each tire-soil interaction model for a horizontal track; iii)
Deploy and evaluate models on different hardware platforms.
Results: Given in terms of computational performance (FLOPS,
execution time, hardware) and capabilities (tire and soil parameter
combinations, longitudinal relaxation length, bulldozing effects).
Conclusions: There is a trade-off between model accuracy,
tuning complexity and computational resources required.
