The presentation gives an overview of the latest development in FTire.

FTire is the leading physical tire simulation model, used by automotive engineers all over the world for higher frequence NVH and road loads calculation in all major MBS and vehicle dynamics software packages.

FTire‘s model fidelity recently has been extended by the introduction of two new modelling extensions. The air volume vibration model covers high frequency forces introduced by air volume dynamics inside the belt. A second extension enables flexible and viscoplastical deformation of the rim, to provide more detailed compliance stiffness in the belt-to-rim contact. These new extensions complement other existing belt state modelization subsystems: tread tribology, tread wear and temperature distribution.  

The new submodels discussed in the contribution aim to widen FTire‘s applicability especially in extremely high-frequent excitation conditions, as well as for extreme loads, up to misuse and even crash conditions.

The presentation also gives a brief overview of FTire's extended features like real-time application, multi-thread execution and full 3D soft-soil contact patch contact mechanics.
