A new tyre-soil interaction model for vehicle simulation on deformable ground

In cooperation with the Ford Research Center Aachen, the new tyre-soil interaction model AS2TM for MATLAB/Simulink was developed by Automotive Engineering, Software and Consulting (AESCO). The model takes advantage of more than a decade of research work in the field of terra-mechanics. In this paper, firstly, the theoretical approach of AS2TM is discussed and the implementation of significant soft soil-elastic tyre interaction effects described and, secondly, the stand-alone model has been investigated and validated for steady-state conditions by using a virtual tyre test environment. Furthermore AS2TM is implemented as an S function into veDYNA applying the TYDEX standard tyre interface. The vehicle dynamic behaviour on deformable ground in a full vehicle simulation is highlighted and a comparison of the predicted vehicle performances on various terrains is presented. For the covering abstract see ITRD E127429.
