Abstract
The present study investigates the impact of studded tires on tire-snow interaction
through finite element analysis. Studded tires are widely used to improve traction on snowy
roads, but the effect of the studs on tire behavior and performance has not been thoroughly
studied. Therefore, a coupled Lagrangian deformable tire interacting with an Eulerian
deformable snow model was implemented. In addition, and in order to validate the tire model a
series of multiple steps simulation procedures such as tire-rim assembly, tire inflation and tire
loading on rigid road have been conducted. Furthermore, the tire has been modeled according to
the existing radial tire structural detail with the addition of studs. On the other hand, snow has
been modeled and validated according to the modified Drucker-Prager cap model while both the
studded and non-studded tires have been modeled with the interaction of snow model. Finally the
results were validated with some experimental data provided from previous works. The study
found that the studded tire was able to significantly improve traction on snow-covered roads by a
minimum factor of 1.17 at -50% slip and a maximum factor of 1.5 at an interval of 50% to 100%
slip, compared to non-studded tire, and that the FEA model accurately predicted the tire's
behavior in these conditions. The results of this study can be used to optimize the design of
studded tires and to improve the safety of vehicles in snowy conditions. Additionally, this
research suggests a solution to the issues with studded tires by analyzing current designs and
presenting a new design for a retractable stud mechanism that can be utilized for a diverse range
of tires.
