Improvement of covered wagons of the “East-West” type by sectioning with a partition
Oleksij Fomin, Alyona Lovska, Andriy Klymash, Mykhailo Keremet The dynamic loading and strength of the frame of the “East-West” type covered wagon were determined. To increase the efficiency of operation of covered wagons in international traffic, it is proposed to improve their frames. This improvement consists in using a sectional partition in the body in […]
Defining patterns in the longitudinal load on a train equipped with the new conceptual couplers
Oleksij Fomin, Alyona Lovska, Oleksandr Kovtun, Volodymyr Nerubatskyi The longitudinal-dynamic load on a railroad train has been studied at its steady motion along the track of a homogeneous profile. A value of the longitudinal loading that a train is exposed to has been established. The calculations were carried out for a train consisting of 40 […]
Substantiating the optimization of the load-bearing structure of a hopper car for transporting pellets and hot agglomerate
Oleksij Fomin, Alyona Lovska, Inna Skliarenko, Yurii Klochkov The strength parameters have been determined for the bearing structure of a hopper car used to transport pellets and hot agglomerate. The calculation was based on a finite element method, implemented in the software COSMOSWorks. Strength reserves of load-bearing elements in a carbody have been determined. In […]
Determining the features of loading the improved bearing structure of a platform wagon for the transportation of military equipment
Alyona Lovska, Oleksij Fomin, Anna Chechet, Olena Soloviova The paper reports the improvement in the bearing structure of a platform wagon that transports military equipment and is involved in artillery fire. A special feature of the platform wagon is the presence of rotary sectors made from a composite material with viscous or elastic-viscous links, which […]
Determination of the dynamic load of the carrying structure of the hopper wagon with the actual dimensions of structural elements
Oleksij Fomin, Alyona Lovska , Pavel Skok , Ivan Rogovskii The object of research is the supporting structure of the pellet wagon with the actual dimensions of the supporting elements. One of the most problematic areas is the determination of the indicators of dynamics and strength of the supporting structure of the hopper wagon with […]
Determination of dynamic loading of bearing structures of freight wagons with actual dimensions
Fomin, Alyona Lovska The determination of the dynamic loading of the bearing structures of the main types of freight wagons with the actual dimensions under the main operating conditions is carried out. The inertial coefficients of the bearing structures of the wagons are determined by constructing their spatial models in the SolidWorks software package. Two […]
ESTABLISHING PATTERNS IN THE DYNAMIC LOADING ON THE BODY OF A SEMIWAGON WITH AN ELASTIC MIDDLE PART OF THE GIRDER BEAM
Oleksij Fomin, Alyona Lovska, Ievgen Medvediev, Halyna Shatkovska To reduce the dynamic loading and prolong the service life of a semi-wagon’s girder beam by improving its fatigue strength, it has been proposed to improve its design. A special feature of the girder beam is that its middle part (the distance between the rear supports of […]
