Abstract: Finite element (FE) tyre models are widely used for predicting tyre characteristics and dynamic properties used for vehicle dynamics simulation for CAE durability, ride comfort and handling assessment. Particularly, tyre FE simulation can be used to predict variation in tyre characteristics which would be too tedious to measure using laboratory tests, such as those due to changes in the tyre reinforcement material or structural layup. The cornering force characteristics of a tyre is one of the most influential factors in full vehicle dynamics simulation, having a significant effect on the directional control and handling stability of the vehicle. A validated FE tyre model developed using ABAQUS was used in parametric studies to determine factors affecting cornering force and aligning moment characteristics using design of experiments (DOE) method. Prediction of the cornering properties of the rolling tyre demonstrated the sensitivity of tyre cornering properties to tyre design parameters and operating conditions.
