Abstract
The article investigated cases of different filling of the tank with oil and without oil. Three winding options were modeled: with one interval between turns, with a double interval and with a triple interval. Two types of winding were considered: from high-strength steel wire and from composite thread. It is found that when wound with a steel wire with a triple interval, the stresses in the structure do not exceed 34.2% of the yield strength. At the same time, the height of the oil filling does not significantly affect its strength. The use of a composite thread leads to an increase in stresses up to 47.2% of the yield strength, but allows you to reduce the weight of the tank with the winding. When winding with a composite thread with a triple interval, the mass of the structure increases by only 3.6%.
