Syntax

data = compute(obj,data)

Description

Add-On Required: This feature requires the Extended Tire Features for Vehicle Dynamics Blockset add-on.

data = compute(obj,data) executes the solver for the model specified by obj using the tire data specified by data.

Execute the tire model solver on input tire data to calculate forces and moments.

Create a built-in Magic Formula 6.2 tire model.

tm = tireModel.builtin("Light passenger car 205/60R15","MF62");

Generate synthetic tire data with a slip angle ramp from -0.15 to 0.15 rad at three vertical load levels. This simulates a cornering stiffness test.

td = tireData.generate("Ramp", ...
    direction="alpha", ...
    initialValue=-0.15, ...
    finalValue=0.15, ...
    Fz=[3000;4000;6000], ...
    kappa=0, ...
    gamma=0, ...
    Vx=16.7, ...
    IP=220000, ...
    psidot=0, ...
    omega=55);

Run the tire model solver to compute forces and moments from the kinematic inputs.

td = compute(tm,td);

Plot the computed lateral force against slip angle for all three load conditions.

plot(tm,Data=td,DataVariableNames=["alpha","Fy"],ColorBy="Fz")

Tire lateral force vs. slip angle graph showing nonlinear cornering behavior at 3000 N, 4000 N, and 6000 N normal loads for a light passenger car tire (205/60R15), with lateral force increasing in magnitude as normal load rises.
