DELFT-TYRE: high frequency tyre modelling using SWIFT-Tyre
other
As is well known, Magic Formula tyre modelling (MF-Tyre is a part of ADAMS/Tire) allows an accurate and efficient description of tyre-road interaction forces required for any usual vehicle handling simulation. When it comes to modelling of tyre behaviour at higher frequencies, which are important for vehicle ride assessment, advanced chassis control systems and chassis system vibrations, a more sophisticated approach is required. In close co-operation with the Delft University of Technology and with involvement of 9 automotive companies, TNO has developed the SWIFT (Short Wavelength Intermediate Frequency Tyre) model, which is based upon a rigid ring type of tyre model. This presentation shows applications of the SWIFT tyre model for ABS braking, the vertical force transfer and the interaction between steering and braking forces on uneven roads.
