A PROPOSED MODEL OF VERTICAL CYLINDRICAL STEEL OIL TANKS WITH REINFORCING WINDING

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%.
