High-speed Friction Predicted Model of Tread Rubber Based on Experimental

The friction behavior of tread rubber directly affect service life of aircraft tires. In this paper, the High-speed friction tester has been developed, and friction tests with different loads and speeds have been carried out. Here, a numerical High-speed friction model is developed based on the tests. Results indicate that the coefficient decreases when the speed and load increase, and there is a power function between the load and the contact pressure. Besides, a High-speed friction predicted model is developed, which considered the influence of contact presure and speed based on the Power function friction model.
