Search design of vehicles in agro-industrial complex

Abstract

The research of problems on estimation criteria development of reliability indicators and durability of transport unibody constructions for agricultural production from the point of view of destruction mechanics proceeding from factors of their initial defect in combination with field investigations under actual operating conditions has been developed. It has been carried out the structural analysis of failures of vehicles which are system components on observance of reliability of transport unibody constructions of wheeled vehicles. Conceptual approaches of search design of construction frames of transport means in agrarian and industrial complex with work resource forecasting are considered, efficiency at the decision of the specified analytical and research and experimental and research problems is proved. A number of tests were performed to determine the dynamic parameters in the most characteristic operating conditions of machines. The obtained statistical data, which allow, with the help of analytical studies, to determine the components of the stress state and the nature of their change over time (average values, maximum and minimum stresses, their frequency, etc.) in accordance with operating conditions. According to the obtained results, the synthesis of load-bearing structures through the formation of such models of service life, which adequately describe the processes occurring during the operation of agricultural machinery was conducted. This approach ensures the transfer of the obtained experimental database (using the developed algorithms in the dynamic and nonlinear formulation of problems) not only to the design of the structure, but also to the analog type of machines. It provides, in combination, forecasting durability optimization of resources, and the modernization and improvement of this type of structures.

Key words: search design, reliability, forecasting, resource, load, transport means.
