Efficiency assessment the braking equipment of freight cars on the Angren-Pap section of the railways.

Based on the study of data on equipment failure at the Angren-Pap section of the railways of the Republic of Uzbekistan, the article systematizes the main malfunctions of the braking equipment of loaded freight cars. Methods of analysis of the scheme and longitudinal profile of the Angren-Pap line are used to identify the most stressed sections in terms of the complexity of the car passage, and to establish the main malfunctions of the brake system. It was stated that the electrified railway line Angren-Pap is an important link not only for railway transport, but also for the entire economy of the Republic of Uzbekistan. It is shown that the main problems are the gross wear of brake shoes and an increase in their temperature. The analysis of malfunctions of the braking equipment of freight cars operated on the Angren-Pap section is performed. The main characteristic problems and malfunctions of the braking equipment of freight cars operating at the Angren-Pap section were identified. The wear of cast iron shoes and the assessment of the dependence of wear on the speed of rolling stock, the wear thickness of the shoes at different heat flux distribution ratios in the shoes and slope ratios were calculated. The critical time of continuous braking was also calculated. Conclusions were drawn on the basis of calculations and damage assessment. [ABSTRACT FROM AUTHOR]
