VDMS Tire Model


VDMS Tour: VDMS TIRE MODEL

VDMS contains the MRA Nondimensional Tire Model implemented in S-Function form. Inputs to the tire model are normal load, slip angle, inclination angle, slip ratio and local surface friction coefficient. The model outputs lateral force, longitudinal force and aligning torque. For a more detailed description of the MRA Nondimensional Tire Model, click here.

The diagrams below show the Simulink subsystems containing the tire model.

Alternate tire models may be substituted into VDMS. If the new tire model is already programmed in Simulink it can be substituted directly inside the Tire Model block. Non-Simulink descriptions may be compiled as S-Functions (DLLs) and inserted.

The VDMS tire model architecture is designed for the replacement of the tire model with user specific (proprietary) tire models. This includes special features in the program initialization to accept new tire models and their input files as well as the convenient one-block tire model in Simulink.
