Andriy B. The optimization of structural parameters of tank supports of the special small-sized sprinkler.

Thesis is devoted to finding the decisions concerning the reliability increasement of the casing constructions (tanks) for agricultural sprinklers by means of designing the pattern and developing of the effective calculational technique for constructional parameters of the lodgment supports, as well as the fastening elements of the tank, and creation of their constructions from the view of durability on this basis. Analytical dependences for the description of the external force have been obtained, and the determination of tensely-deformed state of the cylindrical tank of the sprinkler has been formed. Theoretical bases for determination of the optimized structural parameters of the supporting bases to meet the contract conditions have been developed. Effective engineering technique has been developed according to the solution as for the optimization of the structural parameters of the tank support of a special small-sized sprinkler with extended functional capacities. Experimental research of the stress dynamics has been carried out, and actual tensely-deformed state of the tank case of the considered sprinkler by supporting it upon its typical and suggested supports with high performance efficiency of the later, has been set.
