摘要

Three different reinforcing fillers were selected for winter tire tread rubber. After improving the testing method using the LAT100 testing machine, tests were conducted on the effect of rubber surface roughness on ice grip and wet grip performance, as well as research on the effect of load and speed on the rubber-ice friction coefficient at different temperatures. The results showed that with the increase of the macroscopic roughness of the rubber surface, the frictional force between the rubber and the ice surface decreased, the frictional force between the rubber and the wet road surface increased; With the increase of load and speed, the friction coefficient of rubber on the ice surface decreases, and the change is more obvious on the – 15 ℃ ice surface compared to the – 5 ℃ ice surface, and the friction coefficient on the – 15 ℃ dry ice surface is greater than that on the – 5 ℃ wet ice surface; In order to better predict the results of the real vehicle test, in the LAT ice friction test, the load was selected from 75 to 100N, the speed was selected from 0.6 km/h, and the run-in conditions specifically for winter tread rubber were determined. This provided theoretical support for improving the accuracy of indoor predictions of real vehicle ice grip test results and enriched the research on the rubber-ice friction mechanism.
