Reducing the rigidity of the rubber wheel leads to an increase in the contact area between the rubber wheel and the abrasive belt, the average pressure decreases, the adhesion friction increases, and the friction coefficient shows an increasing trend.

The sentences
The hysteresis loss of the rubber wheel gradually decreased with the increase in the temperature, and when the reduction in the hysteresis friction exceeded the increment in the adhesion friction (about 70 °C), the friction coefficient showed a decreasing trend.
The whole curve showed a trend of bell-shaped distribution; formulas 1#, 2#, and 3# presented the same curve characteristics, but the curves under the conditions of different formulas and factors presented certain differences, which was manifested in the different slopes of the curves, and the initial intercept was also different.
