The article deals with the design of the frame, which will serve to build a new prototype three-wheel vehicle with ecological drive. The proposed frame will be made of aluminum to reduce the weight of a three-wheel vehicle. The new design will allow for optimal distribution of individual parts of an electric vehicle. The 3D model of the frame is created in the CATIA program. The static load calculation will be realized in the ANSYS program.

“…The analysis of publications [6][7][8][9][10][11][12] carried out in this work shows that when designing a new rolling stock, the task of increasing the traction and coupling properties with the improvement of their technical and technological characteristics is put forward. This is possible through the development of scientifically sound technical and technological solutions that accelerate scientific and technological progress in the locomotive economy, including with the maximum possible utilization of the coupling weight of the locomotive [13].…”

The article presents the results of a research of the reserves for the realization of tractive and braking forces of a rail vehicle. Two target functions have been developed that show the evaluation of the design and identify opportunities to increase the efficiency of using the locomotive. On the basis of the objective functions, technical solutions have been proposed and patented in the crew part of the locomotive. The analysis of the factors that affect the traction and coupling qualities of the locomotive was carried out. A mathematical modeling of the starting from the place of the shunting locomotive TEM103 was carried out. The redistribution of loads from wheel pairs to rails is shown depending on the speed. The change in the wheel-rail contact area when the load of the shunting locomotive TEM103 changes is estimated. The work of the proposed finish loading device in different modes of operation is described. Efficiency of work is shown.

The geometric relation between a wheelset and a rail is assessed with the help of geometric characteristics. Geometric characteristics are: equivalent conicity function, delta r function placement of contact points of a wheelset and a rail, tangent gamma function and effective conicity. It turned out that these characteristics are at present the most important not only for the judgment of ride characteristics of a vehicle on the rail but also for the wearing of wheel treads and rail heads, e. i., for the assessment of the track and vehicles in order to find out the current state and for the assessment of changes of the wheels and rails profile shapes in order to improve the current state too. The process of geometric characteristic assessment of a wheelset and rail with regard to wheelset rolling, as well as contact forces are analysed in the article.
