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

“…The presence of the material with viscoelastic properties in the girder beam was modeled by installing the "spring-damper" links between the rear stops of the autocoupling devices using relevant options from the SolidWorks Simulation software package. The model was fixed in the areas where the bearing structure rested on the running parts [47][48][49][50]. The results of strength calculation are shown in Fig.…”

This paper reports a study into determining the dynamic load and strength of the bearing structure of a covered freight car under operational modes. A feature of the freight car's bearing structure is that the girder beam has a closed cross-section. To reduce the dynamic load of the frame, the girder beam is filled with a material with viscoelastic properties. Such a solution could contribute to the transformation of the kinetic energy of impact (due to jerk, stretching, compression) into work of viscoelastic friction forces, and, consequently, to reducing the load on the bearing structure. To substantiate the proposed improvement, the dynamic load on the bearing structure of a covered freight car was mathematically modeled. The calculation was performed for the case of joint impacts at shunting. The study was carried out in a flat coordinate system. It was established that the maximum accelerations acting on the bearing structure of a covered freight car were about 37 m/s2. The calculated acceleration value is 3.2 % lower than that obtained for the bearing structure of a covered freight car without filler. The results of calculating the strength of the load-bearing structure of a covered freight car are given. In this case, a finite-element method was applied. The maximum equivalent stresses occur in the zones of interaction between the girder beam and the pivot beams, and amount to 319.5 MPa, which is 8 % lower than permissible. The calculation was also performed regarding other operational modes of loading the freight car's bearing structure. The model of the dynamic load on the bearing structure of a covered freight car was verified according to the F-criterion. The research reported here could contribute to designing innovative rolling stock structures, thereby improving the efficiency of their operation.

For the implementation of a mixed type of transportation on the territory of Ukraine, a stable saddle for transporting cargo semi-trailers without a tractor on railway platforms of the 13-9004M model was developed and manufactured. This device for the transportation of cargo semi-trailers is a four-sided structure of the "Eiffel Tower" type, the lower plane of which is fixed on the platform car through the plate with the help of bolted connections. This work describes the running tests of the 13-9004M model platform car with a saddle rack installed on it for the transportation of cargo semi-trailers without a tractor. According to the results of the tests of the saddle rack for the transportation of semi-trailers on the platform wagon model 13-9004M, the maximum values of the stresses that occur in the structure of the saddle rack during running strength tests, as well as compliance with such indicators as the coefficient of vertical dynamics of the sprung mass of the cart, the coefficient of vertical dynamics of the unsprung mass, were determined trolley frame, coefficient of horizontal dynamics, coefficient of reserve of stability of the wheel from derailment.
