For the developed design of a small-sized self-propelled sprayer, it is proposed to use a tank from which the working fluid is displaced under pressure in the power system of the spraying devices. For the safe operation of such a shell, a method of determining its stress-strain state has been developed. The main analytical dependences are based on the principles of the momentless theory of shells. The results of the calculations are the determined numerical values of stresses in the cylindrical part of the shell and its bottoms. Similar results were obtained when simulating the operation of such a tank using the SolidWorks2019 application program. A comparative analysis of the obtained numerical values of the studied quantities was performed. Recommendations have been made regarding the method of securing the tank to the sprayer frame.
