For CarStat I want to visualize a graph showing the thermal degradation of the tires. A picture is worth a thousand words, so here's what I got so far: How do I get these lines: I use the DegradationCurveParameters and DegradationPerUnitHistory values to calculate the grip % for a specified time (eg 10 mins). So Example: Code: I've got these parameters: DegradationCurveParameters=(338.15,2900) DegradationPerUnitHistory=(1,0.979,0.967,0.96,0.956,0.9535,0.9512,0.949,0.9469,0.9449,0.943,0.9411,0.9392,0.9373,0.9354,0.9335,0.9316,0.9297,0.9278,0.9259,0.924,0.9221,0.9202,0.9183,0.9164,0.9144,0.9122,0.9097,0.9066,0.9023,0.897,0.892) If I want to calculate how much % of grip (thermal, not wear) I have left after running 10 minutes at a constant 89 °C (20 °C above the 338.15 K activation temp) I've got: HeatHistory = (10min x 60) x 20 °C = 12000. Every heat history-step costs 2900, so with 12000 I'm at step 4. Step 4 = 0.956 or 95,6%. My questions are: - DegradationPerUnitHistory has 32 values for 32 HeatHistory-steps. What happens after this? Does the tire explode? Does it stay at value 32? Something else? - The 99 °C line (and the 89 one) in the example above already reaches the 32th value after 50 minutes (hence the line that stops). The optimal temp of this tire is 100 °C, so this would mean that after 50 minutes of driving at the optimal temp the tire would be shot. Isn't that rather quick? I hope someone can answer these questions. If the above isn't clear, please ask me more information.
Looks like I made a mistake somewhere in the calculation, this looks a lot more realistic to my amateur eye: The first question remains however: what happens after the end of the line?
Personally I think nothing happens. The degradation remains at the end value. Grip loss due to wear obviously still continues. Just a hunch though.
