Adams Tire Data and Fitting Tool
The Adams Tire Data and Fitting Tool (TDFT) can calculate PAC2002 or PAC-MC tire model parameters out of tire measurement data or virtual test data for steady-state pure and combined slip conditions, for the basic properties and (for PAC2002 only) enveloping and belt dynamics parameters including the possibility to visualize/modify tire characteristics.
Tires added to the Tire Data Tool can be saved to a tire database file. Each tire in the tire database can be exported to a PAC2002 or PAC-MC tire property file that can be used with Adams Tire.

Plot Parameters: | |
Basic | For plotting the basic tire properties such as loaded radius, effective rolling radius, relaxation length and contact patch length and width. |
Force/Moment | For plotting the steady stated force and moment response of the tire on variations of load, slip, camber and inflation pressure. |
Advanced | For plotting the tire advanced (transient) properties such as non-rolling longitudinal or lateral tire stiffness, or the parking torque at stand-still. |
Enveloping/Belt | For plotting the force response of a tire when rolling over a cleat at fixed axle height (PAC2002 only). |
Plot | Select: ■Embedded or ■Adams PPT for plotting of the tire characteristics. |
Measurement Data | Select: ■Yes: Use tire model input data from the measurement data files and plot measurement data. ■No: Use tire model input data as defined in Plot Parameters. |
Slip Condition | Select: ■Pure: Pure slip conditions. ■Combined: Combined slip conditions. |
X-axis | Variable on X-axis (for example, Longitudinal Slip). |
Y-axis | Variable on Y-axis (for example, Fx). |
Vertical Load | Tire vertical load (for example, 2000, 3000, 4000). |
Longitudinal Slip | Tire longitudinal slip (for example, -1:0.01:1). |
Lateral Slip Angle | Tire lateral slip (for example, 0). |
Inclination Angle | Tire inclination angle (for example, 0). |
Inflation Pressure | Tire inflation pressure (for example, 200000,220000). |
Forward Speed | Forward speed of the tire (for Basic or Enveloping/Belt plot). |
Cleat Geometry | For defining the cleat height, length, bevel edge and orientation angle (for Enveloping/Belt plot). |
