Tire Simulation & Testing

Tire Simulation & Testing

The tire is a complex and highly non-linear vehicle component that has a significant effect on the behavior of a vehicle. As the number of vehicle models on the market continues increasing, so does the number of possible use cases that need to be tested and validated. This fact, in combination with everlasting strive for reduced development times, calls for ever more simulation instead of physical vehicle testing.

Modelling tire performance requires a lot of expertise and specialization. For this purpose, Simcenter offers engineers scalable and customized solutions. The ultimate goal of Simcenter Tire is to accurately represent tire forces and moments, so they can be propagated to various vehicle performance simulations.

More specifically, the Simcenter Tire toolchain consists of the Simcenter MF-Tyre/MF-Swift tire model, the Simcenter MF-Tool tire model parameterization tool and tire testing services. The Simcenter MF-Tyre/MF-Swift model is available with all major vehicle dynamic simulation packages.

MF-Swift

Analyze all vehicle dynamics using an all-in-one tire model. Simcenter MF-Swift extends MF-Tyre with turn slip modeling, tire belt dynamics and generic 3D obstacle enveloping for parking, ride comfort, road load prediction, and vibration analysis. The modular setup allows the model complexity to be adapted to the engineering problem. Simcenter MF-Swift is the fastest tire model on the market for 3D uneven road simulations. Thanks to its transparent structure, engineers can easily tune or estimate parameters during early development, when no physical tires are available. Its modeling functionalities have been developed and extensively validated using numerous measurements, experiments and customer use cases.

MF-Tyre

Accurately simulate steady-state and transient behavior up to 8Hz, for handling, control prototyping, and ADAS analyses. Simcenter MF-Tyre is the global standard implementation of the Pacejka Magic Formula, including the most recent modeling developments such as inflation pressure effects, estimated combined slip behavior and a non-linear representation of tire transient behavior. MF-Tyre is the only Magic-Formula-based tire model that is available in all major vehicle dynamic simulation packages, allowing in- and intercompany standardization.

Real-Time

Convert a Simcenter MF-Tyre/MF-Swift model into a real-time variant without model reduction, to guarantee equal numerical results across all stages. Over the course of the product development trajectory, various simulation environments pass by, including desktop applications, HiL setups, and driving simulators. Simcenter helps engineers use a standardized tire model across all simulations, by adapting the model to the required computational performance without affecting results. Consequently, Simcenter MF-Tyre/MF-Swift is currently supported on most industry-standard Real-Time operating systems.
