The study focuses on the prediction technology of rubber block friction properties on ice. The 2-D simplified block model with sipes (narrow grooves) and the mechanical analysis methodology are applied to understand the complex tribological phenomena and improve winter tire grip on icy roads. The friction forces on ice are assumed to consist of adhesion force. viscous drag of water film. https://lecoureures.shop/product-category/ski-de-fond-homme-vetements-manteau/
