The practice of designing mine drums is based on the introduction of additional stiffening elements, such as ribs, rings and scarves. This significantly increases the weight and complexity of the drum manufacture, and also leads to local stresses in the welded areas. This greatly complicates the operation of the structure and leads to the destruction of welds and the appearance of cracks. Reinforcing the welds does not improve the situation, but rather reduces the durability of the drum shell. Designers of mine hoisting machines do not have a theoretical basis for refusing to install rings and stiffeners. The calculations of the strength of the drum head using the simplified and refined methods showed that the strength of the head is fully ensured and there is no need to install additional structures in the form of scarves.enmine drumfrontal linershellstrengthbending momentstressscarfstiffening elementsшахтний барабанлобовинаобичайкаміцністьмомент згинуArticle621.86310.30977/BUL.2219-5548.2023.101.2.142
