Kovbasa V. 3. The mechanic-technological justification of optimization of interaction of tools with soil

In a thesis on the basis of plurality of generalized results the actual scientific problem is solved which consists in development of the new concept of parameters optimization and tool's modes of operations of machines, interacting with agricultural materials and mediums, on the basis of solution of the spatial contact problems of with infinite boundaries.The analysis of methods of soil formalization as object, on which operate the tools of tillage machinery is carried out. The model of soil's deforming during interaction with it of tools is designed and the physical connection equations of stress with strains in two phases of a deforming (elastic - viscous inverse and viscous-plastics current) are obtained.The solution of a spatial contact problem of tools with soil has allowed receiving dependences of connection of a strains distribution and stress in a soil's half-space before a tool.As a result of the carried out researches the functional connections of distribution of pressure on a surface of tools and power consumption of process depending on parameters, modes of operations of tillage tools and soil's properties were received.The adequacy of theoretical researches is confirmed by results of experimental researches.The function is obtained and designed a procedure and program for embodying algorithm of optimization of parameters and modes of operations of tillage tools for different states of soil.
