    • Road Modeling

    • Tire Modeling

      • Introduction to Tire Modeling

        Tires are critical elements to modeling a vehicle’s interaction with a road, with some tire models better suited to specific simulation domains.

      • Coordinate Systems and Output Requests

      • Multi-Threading and Tire Models

        Since computing tire forces and moments during a vehicle simulation is one of the most costly tasks, multi-threaded execution of tire models on a multi-core computer can substantially reduce the clock time for a simulation.

      • CDTire Modeling

        Altair HyperWorks integrates the Comfort and Durability family of tire models - CDTire - from Fraunhofer ITWM. As the name implies CDTire focuses on comfort and durability applications, however it also allows for handling analysis as well.

      • Fiala Tire

        The FIALA tire model serves as the first stepping stone in full vehicle simulation because it is simple enough to be comprehended completely by the MBD analyst. Furthermore, the forces and torques produced by the tire/road interaction use a series of physically meaningful parameters.

      • FTire Modeling

      • MF-Tyre/MF-SWIFT Modeling

        Altair HyperWorks integrates MF-Tyre and MF-SWIFT tire models from Siemens (branded by Siemens as Simcenter Tire).

      • User Written Tire and Road Models

        User Written Tire models are implemented as user subroutines that compute the tire forces and moments, and the user road model is implemented as a subroutine that computes the road height at a given point.

        • Writing Tire Models

        • Writing Road Models

          User Written Tire models are implemented as user subroutines that compute the tire forces and moments, and the user road model is implemented as a subroutine that computes the road height at a given point.
