Altair Enhanced Fiala Tire for Durability

This white paper details a new tire model available in MotionSolve. This tire model can be used to generate durability loads and evaluate secondary ride with better accuracy than a simple point-follower road contact method. It utilizes a reduced set of input parameters when compared to high fidelity tire models. The level of physics complexity is reduced, which may tend to reduce accuracy for detailed simulation, but this model serves as an interim step toward more complex tire models, which require expensive physical testing to populate with input data. This paper begins with an introduction about the tire model itself, and then ends with an overview of the testing required to populate the tire model, and a comparison of test vs. simulation.
