Prediction of Tire Cornering Behavior with An Enhanced Friction Model

A detailed tire cornering model using the implicit to explicit FEA solving strategy is constructed. The actual rubber distributing, non-linear stress-strain relationship of rubber and bilinear elastic reinforcement are modeled to avoid a departure from the reality. A tread rubber friction model obtained from a Laboratory Abrasion and Skid Tester (LAT 100) is applied to simulate the interaction of the tire with the road. To demonstrate the efficiency of the proposed simulation, computed cornering forces for a 185/75R14 tire are compared with results by the implicit solver as well as experimental results from a MTS Flat-Trac Tire Test System. The computed cornering forces agree well with experimental results.
