Abstract:

Purpose. Highlighting the results of the analysis of the stress-deformed state of the wagon body of the 918 model under non-typical loads with bulk cargo. Such an analysis was carried out with the aim of investigating the possibility of transportation of various types of bulk cargo (for example, various types of raw materials, agricultural products, construction materials, etc.) in the existing design of the section of the refrigerated wagon.

Methodology. In order to ensure uninterrupted railway transportation in today’s difficult conditions, it is proposed to use scientific and applied approaches to develop the possibility of using existing models of wagons for types of transportation that are not typical for them. Namely, to consider the possibility of using refrigerated wagons for the transportation of bulk cargo. A systematic approach is used to conduct such research. This included: determination of the study of the specifics of the impact of bulk cargo on rolling stock structures; analysis of design and technological documentation to create a spatial 3D model of the wagon under investigation; creation of a calculation model using a modern software complex; checking the adequacy of the developed model and the accuracy of the data obtained with its help; application of non-typical design loads; obtaining and analyzing pictures of stress-strain states by the finite element method.

Findings. A 3D model of the body module of the model 918 wagon was developed. The results of the analysis of the equivalent stress plot according to the first mode proved that the greatest stresses are 800 MPa, that is, they significantly exceed the permissible ones. According to the third mode, the highest stresses are 320 MPa and also exceed the permissible ones. The results of the analysis of the plot of equivalent stresses, which occur during expansion, proved that the loads are excessive. The cladding, supported only by racks, cannot hold the load from the bulk cargo.

Originality. A strength analysis of the existing design of a refrigerated wagon section was conducted under non-typical bulk cargo loads.

Practical value. The obtained results of the analysis of the stressed-deformed state of the body of the model 918 wagon when loaded with bulk cargo made it possible to assess the potential possibilities of such transportation. It is expedient to use such results when carrying out research and development works on the improvement (modernization) of the existing sections of refrigerated wagons to ensure the possibility of transporting bulk cargo in them. This, in turn, will increase the efficiency of the domestic fleet of freight wagons.

Keywords: mechanical engineering, freight wagons, strength calculations, bulk loads
