ESTIMATION OF THE EFFICIENCY OF THE BRAKING EQUIPMENT OF FREIGHT CARS AT THE SECTION OF ANGREN-PAP OF RAILWAYS OF THE REPUBLIC OF UZBEKISTAN

Аннотация

The paper systematizes the main malfunctions of the braking equipment of loaded freight cars based on the study of data on equipment failure on the Angren-Pap section of the railways of the Republic of Uzbekistan. The methods of analyzing the scheme and the longitudinal profile of the Angren-Pape line are used to identify the most stressed sections in terms of the difficulty of passing cars, as well as to establish the main malfunctions of the braking system. It has been established that the electrified Angren-Pap railway line 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 significant wear of brake pads and an increase in their temperature. The analysis of malfunctions of the braking equipment of freight cars operated on the Angren-Pap section is carried out. The main characteristic problems and malfunctions of the braking equipment of freight cars operated on the Angren-Pap section have been identified. The calculation of the wear of cast-iron pads and the assessment of the dependence of wear on the speed of movement of the rolling stock of the wear of the pads in thickness at different coefficients of the distribution of heat flow in the pad and slopes are given. The calculation of the critical time of continuous braking is also made. Conclusions were drawn based on calculations and evaluation of malfunctions.
