Purpose. The proposed study is aimed at determining the strength indicators of the hatch cover of universal gondola car with intermediate S-shaped strapping made of polytypic materials under operational loading schemes. Methodology. To achieve this goal, it has been proposed to create a fundamentally new hatch cover design for a gondola car. A feature of the hatch cover is that it consists of two leaves, which along the perimeter interact through the S-shaped strapping. The calculation was carried out using the finite element method implemented in the software environment of CosmosWorks. Findings. The strength indicators of the improved hatch cover design are obtained under operating schemes of its loading. The basic schemes of loading the hatch cover of the gondola car in accor-dance with the normative documents have been adopted, as well as additional ones. To the additional the following are classified as: simulating the opening of the hatch cover during operating loading - the torsion-free (without operation of the torsion (s)) non-simultaneous impact on the supports of the intermediate car frame beam with the maximum opening angle; non-simultaneous opening of the door latches - the hatch cover of the loaded car is supported by door latch for one bracket (the case when one has already knocked out one door latch and the other has not yet had time); pulling (closing) the hatch cover of the unloaded gondola car with a crowbar. It is established that the strength of the hatch cover is ensured. Originality. A developed strength model of the improved hatch cover design of the universal gondola car makes it possible to obtain indicators of its strength under operational loading schemes. The results of the carried out research can be used at designing of bearing designs of bodies of universal gondola cars of new generation with the improved technical and economic indicators. Practical value. The results of the research will contribute to ensuring the strength of the structural elements of the gondola car bodies in operation.
