Novel methodology for data processing on friction models with validation

Tyre grip is dramatically affected, among many parameters, by viscoelastic material behavior of tread compound and road roughness and how these parameters are measured and processed. Here we propose a practical and standardized methodology, developed with Pirelli, for acquiring and processing surface data, combined with a technique of tire tread non-destructive viscoelastic characterization. The results of the friction models are validated on data obtained with a new Linear Friction Tester.
