Therefore, when calculating fertilizer spreaders bearing structures necessary to apply the newest scientific achievements of corrosion - fatigue strength structural materials, welds elements and layout of machines of this class as a whole. The obtained scientific results confirm the theoretical and practical foundations of new scientific knowledge, accordingly, the theory describing the processes of destruction lifting system trailed spreaders of organic fertilizers in terms of cyclical workloads and corrosion - aggressive environment, the basis of which the charged developed computational models, as well as to this database, created new trailer carrying frame making machines for solid organic fertilizers with improved performance durability and strength. Done analytical model of stress - strain state of structural elements frames trailed fertilizer spreaders, taking into account the actual loading conditions and taking into account corrosion - fatigue its damage. The choice of evaluation criteria corrosion crack resistance of structural elements, constructed new mathematical model to describe the stress - strain state of thin profiiv cracked. The features corrosion and electrochemical behavior of engineering steels in environments fertilizers. Characteristics of fracture design materials in aggressive environments. Based on the energy approach built computational models to determine the durability of structures farm machinery under the action of cyclic loads and operating corrosion - aggressive environment at zarodzhennnyah and development of corrosion and fatigue damage. On the basis of comprehensive studies suggested upgrading carrying fertilizer RTD system in which ensured uniform in size, with a reduction to 25% without nets, the distribution of stresses in sections along the perimeter of the carrier system, improved durability performance while decreasing metal 58 kg. a significant increase in performance and manufacturability.
