Abstract

Snow is a complex material. Its mechanical properties are influenced by various factors such as ambient temperature, solar radiation, compaction, metamorphism, etc., making it complex to model and predict them. To date, only a few studies have focused on predicting the traction coefficient as a function of ambient temperature, snow temperature, and snow compaction (CTI Index). These parameters are measured in accordance with The ASTM F1805 standard, which is used to evaluate the straight-line tractive performance of tires on snow.

This study introduces an additional parameter: spin count and investigates its effect on tractive performance. It was observed for the 16-inch SRTT that the traction coefficient of the control tire decreased progressively as the season advanced. The study aims to determine whether a similar trend applies to a 14-inch SRTT and correlates the tractive performance of individual control tires with ASTM F1805 parameters using regression analysis. Furthermore, it seeks to identify the most accurate regression algorithm for predicting the tractive coefficient and ranks the most influential parameters through feature selection.

In summary, this research examines the influence of spin count on tire traction, aiming to improve prediction models and identify key parameters influencing performance on snow.
