| dc.description.abstract | The purpose of the study is to evaluate the effect of cooling frictional surfaces on the efficiency of the braking system by experimentally determining the coefficient of friction and the temperature of the interacting surfaces under different methods and regimes of cooling. Experimental research established that the mathematical model of the disc brake thermophysical characteristics, which takes into account the adaptive cooling system, ensures a satisfactory match of the results of calculations to experimental data; the discrepancy does not exceed 10-12%. Analysis of the experimental data obtained allows concluding that adaptive cooling of the brake friction surfaces has a positive effect on the braking efficiency. Thus, the coefficient of friction when using this system is 15-30% higher, depending on the performance and temperature of the cooling air, than without its use. The average integral temperature of surfaces in frictional interaction is lower by average of 20-30% compared to the case when adaptive cooling is not used. | |
