To increase the efficiency of using railway transport, the possibility of using new designs of bogies, for example, Y25 under "wide gauge" wagons was considered. In order to substantiate the proposed solution, mathematical modeling of the dynamic loading of the hopper wagon Y25 bogies was carried out. A hopper wagon for the transportation of pellets and hot sinter model 20-9749 built by the State Enterprise "Ukrspetsvagon" (Ukraine) was chosen as a prototype. The simulation results showed that the use of Y25 bogies for hopper wagons allows to reduce the acceleration of its load-bearing structure, in comparison with the use of conventional 18100 bogies, by 36 %. Other performance indicators are also significantly improved. The use of Y25 bogies for hopper wagons with actual parameters allows to reduce the acceleration of its load-bearing structure, in comparison with the use of conventional 18100 bogies, by 28 %. The determination of the main indicators of the strength of the bearing structure of the hopper wagon Y25 bogie was carried out. The calculation was carried out in the SolidWorks Simulation software package (CosmosWorks), (France), which implements the finite element method. The calculations showed that the maximum equivalent stresses in the load-bearing structure of a hopper wagon with nominal parameters are 17 % lower than the stress acting in the load-bearing structure of a wagon on bogies 18–100 V of the load-bearing structure of a hopper wagon with actual parameters, the maximum equivalent stresses are 12 % lower per voltage in the load-bearing structure on bogies 18100. The conducted research will help to reduce the load on the load-bearing structures of hopper wagons in operation, improve the dynamics and strength indicators, as well as their service life

The article reflects the results from determining the vertical loading of the supporting structure of the tank car. A feature of the tank car is the presence of friction bonds implemented by means of elastic elements in the boiler supports on the frame, which helps to reduce the loading of the supporting structure and increase the fatigue strength. To substantiate the proposed solution, the determination of the vertical loading of the supporting structure of the tank car was carried out when driving in an empty state by rail unevenness. It was established that the use of friction bonds implemented by means of bearings makes it possible to reduce the dynamic loading of the tank car by almost 35% compared to the prototype. To determine the distribution fields of acceleration acting on the supporting structure of the tank car, as well as their numerical values, a computer simulation of the dynamic loading of its supporting structure was carried out. The calculation was carried out using the finite element method according to the Mises criterion. When carrying out calculations, elastic connections were placed between the boiler and its supports using the options of the software package. To consider the friction component, the friction force was taken into account which was applied in the zones of the interaction of the boiler with the supports. The conducted studies showed that the discrepancy between the results of analytical and numerical modeling is 7.9%. It was established that the design service life of the improved supporting structure of the tank car is more than 20% higher than the service life of the prototype car. The safety factor of fatigue strength was 4.1. The research conducted can be used by those concerned about reducing failures in the bearing structures of tank cars in operational loading modes, decreasing maintenance costs, and developing recommendations for designing innovative car structures.
