The object of research. The object of research is the processes of occurrence, perception and redistribution of loads in the design of a container with a frame made of square pipes and lining made of smooth sheets. Investigated problem. Under operating conditions, damage to containers may occur due to the loads acting on them during transportation by various modes of transport. One of the most determining among such loads are dynamic loads, which are experienced not only by the container structure, but also by the cargo placed in it. As a result, there may be damage to the structure of the container, as well as to the cargo, which necessitates additional costs, both for the repair of containers and for reimbursement of expenses for damage to the transported cargo. In addition, this situation is unfavorable from an environmental point of view. In this regard, there is a need to conduct research to improve the design of a universal container in order to reduce its load, as well as increase operational efficiency. The main scientific results. A scientific substantiation of the use of square pipes as components of the frame of a universal container has been carried out. The area of practical use of research results. The sphere of practical use of the obtained results is the engineering industry, in particular railway transport. Innovative technological product. The concept of a universal container with a frame made of square pipes and a lining made of smooth sheets. Scope of the innovative technological product. The developments proposed as part of the study will be useful recommendations for creating innovative vehicle designs, including modular ones.

“…There may be casting cavities that lead to the initiation of cracks [3]. Welded structures of frame elements are also known [4,5], in which fatigue stresses of welds arise, the prediction of which is advisable to carry out using computer simulation. Elements of the supporting body structure may be damaged as a result of shunting operations, docking or loading of cars [6].…”

One of the safest types of public transport is the metro, which is actively developing in many countries. Despite a number of advantages, the construction of metro tunnels is a rather labor-intensive process, which involves complex technical equipment in the form of tunnel boring complexes. Tunnel boring complexes include locomotives that perform the functions of hauling away rock using trolley with removable body. Trolley differs from their usual characteristics - in weight, dimensions, as well as the component composition of individual systems, in particular the compressed-air braking system. The article is devoted to the analysis of the parameters of the stress-strain state of one of the main load-bearing elements of a trolley- the casing. As a result of the analysis, design loading cases were selected, the most loaded parts of the body were determined, recommendations were formed for choosing the optimal material thickness of various elements and increasing the load-bearing capacity of the body.
