Prediction Technology of Rubber Block Friction Properties on Ice

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 gorra artesanal 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, and ploughing effects of sipe edges.Based on this assumption, the ice temperature distribution and friction coefficient in the contact patch are predicted.

The effects of sipe density and block stiffness on tire tread pattern are evaluated.Experimental results partially validated the predicted friction coefficients.The study also proposed new sipe structures with high-density short sipes to improve shure ua874 ice performance.Tentative test results indicate the effectiveness of these new structures.
