Аннотация (краткое описание)
The article discusses the forces that arise when a TE-33A diesel locomotive moves through a switch. The analysis of dynamic loads acting on rail threads, crosspieces, and other switch elements is carried out. The purpose of this article is to determine the efforts of the TE-33A diesel locomotive acting on the main elements of the railway track switch. The measurements were carried out in accordance with the requirements using a strain gauge measuring and computing complex consisting of certified and verified measuring instruments from the world's leading manufacturers. As a result of theoretical analysis and experimental studies, the lateral and vertical forces transmitted by the wheels to the inner and outer rails of the transfer curve were determined when the TE-33A locomotive was moving along the R65 mark 1/11 switch. Possible causes of increased wear of the switch elements under the influence of the TE-33A diesel locomotive have been identified. Recommendations are proposed to reduce the negative impact on the switches, including optimizing driving modes. Based on the results obtained, diagrams of vertical and transverse forces were constructed, and indicators of the stress rate at maximum speed along the arrow of the locomotive in question were established.DOI

In the course of the experimental study, the following results were obtained: 1. An overview of the specifics of the establishment and location of railway switches in the territory of Kazakhstan is provided. 2. To achieve this goal, the lateral and vertical forces acting on the inner and outer rails of the switches were determined experimentally, and graphs of the dependence of the voltage of each wheelset of a locomotive on the speed of movement were constructed. 3. As a result of the analysis of the above dependencies, it was found that the dynamic tensile stresses (the maximum probable value) at the edges of the sole of the rail in the modes under consideration do not exceed: Thus, the lateral forces in the switch type R65 mark 1/11 in the front reach of the frame rail and in the transfer curve, in terms of the maximum observed values up to a speed of 40 km/h, meet the permissible standards, and at a speed of 50 km/h, exceed the permissible standards. The results of the study can be used in the design and modernization of switches, as well as to optimize the operational modes of locomotives, which ultimately contribute to improving the safety and efficiency of railway transport.Квартиль
