Abstract

The object of research is the processes of occurrence, perception, and redistribution of loads in the supporting structure of a gondola car with unloading hoppers. In order to increase the carrying capacity of the gondola car, and accordingly the profitability of railroad transportation, it has been proposed to improve its structure. This improvement implies the installation of unloading hoppers in its middle part. According to preliminary calculations, the use of unloading hoppers could increase the usable volume of the body by 2.82 m3. At the same time, the carrying capacity of the car would increase by 3.8 tons. Accordingly, the axial load on the wheelsets would increase. It is possible to solve this issue by using wheelsets with increased axial load in bogies.

As part of the research, a mathematical modeling of the vertical dynamics of the gondola car during its movement in the empty and loaded states of the rail track was carried out. It was established that the movement of the car is evaluated as "excellent". The calculation of the strength of the gondola car body under the main operational load modes was carried out. The stability of the car's equilibrium was determined, and its modal analysis was also carried out.

The peculiarity of the results within the framework of the study is that the proposed improvement could be implemented not only when designing a new car structure but also during modernization.

The area of practical application of the results is the machine-building industry, in particular, railroad transport. The conditions for the practical application of the research results are compliance with the axial load within the permissible values.

The research reported here will contribute to improving the technical and economic indicators of cars, as well as increasing the profitability of railroad transportation
