Vehicle engineers and tire experts from around the world recently visited FKA (Forschungsgesellschaft Kraftfahrwesen Aachen) in Aachen, Germany, to exchange their experiences with the FTire model and discuss varying applications and future demands together with its creator, Professor Gipser.
This year the seminar focused on all kinds of FTire applications in the CAE process chain, implementation on HiL test rigs, as well as the latest findings from automotive research projects and FTire interfacing with third party simulation environments.
Nowadays alternative full vehicle models are not only used to analyze the performance of a vehicle, they are also used for enhanced durability and ride comfort investigations, for instance.
FTire is one of the most common tire models for this task. It is designed for vehicle comfort simulations on road irregularities even with extremely short wave-lengths. At the same time, it can serve as a physically based, highly nonlinear and dynamic tire model for handling characteristics under the above mentioned excitation conditions.
In contrast to other widely used tire models, FTire explains most of the complex tire phenomena on a mechanical basis – and not merely by mathematical description of measured characteristics.
