“…The verification was carried out by comparing two samplings (Table 2) obtained analytically and with computer modelling. The area of the pad was determined using the spatial model of the pad created in SolidWorks [18][19][20][21][22]. In this case, the nominal parameters of the 2TR-11 brake pad were taken into account, i.e.…”

The work highlights the results of a study into the dual wedge-shaped wear of composite brake pads for freight wagons. It has been found that the overnormative wear makes the area of a composite brake pad larger in the lower part up to a value directly proportional to the wagon mileage and smaller in the upper part. To assess the braking efficiency of a rail vehicle, a graphical analytical method has been developed; it allows determining the factor of dual wedge-shaped wear of pads depending on the wagon mileage. The results of calculation were verified by comparing two samplings obtained by mathematical and computer modelling. The results of calculation have proven that the hypothesis on the adequacy is not rejected. The results of the study conducted will allow more accurate assessment of the braking efficiency of freight rolling stock to be made, as well as contribute to improving the safety of train traffic.

“…Railroad transport has long been a leading component of the transportation industry, which provides for the development of economies in many European countries [1,2]. In order to maintain the branch of primacy, as well as to meet the needs of the economy, it is important to put into operation modern designs of freight cars with improved technical and operational indicators [3][4][5].…”

The object of research is the processes of occurrence, perception, and redistribution of loads in the structure of a removable module for the situational adaptation of the flat car, model 13-7024, to the transportation of strategic cargoes. In order to transport strategic cargoes, including military equipment, agricultural machines, etc., the use of a removable module is proposed on the flat car. Appropriate calculations were performed to determine parameters for the structural components of the removable module. At the same time, the profile of the frame was determined by the value of the maximum bending moment acting in its cross-section. The thickness of the sheet, which forms a horizontal plane for placing the load, was calculated according to the Bubnov–Galyorkin method. To substantiate the determined parameters of the structural components of the removable module, its strength was calculated. The calculation results showed that the strength of the removable module under the considered operating load schemes is ensured. A feature of the research results is that the use of the proposed structure of the removable module makes it possible to expand the range of goods transported by flat cars without improving them. The field of practical use of the results is the engineering industry, in particular, railroad transport. The conditions for the practical application of the research results are the use of variable height fittings in the removable module. Our studies will contribute to devising the recommendations for increasing the efficiency of the operation of flat cars through their situational adaptation to the transportation of strategic cargoes. In add, the results could prove useful for the construction of modern structures of modular vehicles

Design of a device to simulate environmental influences on the course of brake tests

et al. 2018

When performing the technical tests of the brake system under laboratory conditions, it is necessary to create the same conditions as those in operation. The friction coefficient is dependent on a number of parameters, including airflow during ride and weather conditions. Therefore, during the take-over tests, both these conditions are obligatory to simulate. This paper describes the design of the chamber, which will allow the test stand RAILBCOT to carry out the so-called dry and wet tests with airflow as during real-life ride. It also isolates the acoustic emission and emission of braking material to the surrounding area when tested.
