Information × Registration Number 0213U000702, 0110U002702 , R & D reports Title Justification of construction parameters and regimes of energysaving of the soilcultivated of works parts. popup.stage_title Head Kovbasa Volodimir Petrovich, Registration Date 05-03-2013 Organization National agricultural university of Ukraine popup.description2 Work is devoted to researching of process of interaction of disk working bodies of soil-cultivating cars with a soil and optimization of high-speed modes of movement of machine-tractor units which are aggregated by soil-cultivating cars with working bodies of disk type. The offered mechanical model and the developed physical equations of communication of stress with speeds of deformations for soil that has renders essential display of a dry and viscous friction in spatial statement. Solution of contact problem of interaction of disk working body with the soil has allowed establish communications of stress, that arise on the surface of the working body and components of resistance of the soil, depending on the constructive and kinematics parameters of disk working bodies and mechanical properties of the soil. Considering essential influence of forward speed of conveyance of the machine on traction resistance the variation problem by definition of optimum high-speed modes of movement of the machine-tractor unit taking into account a variable relief of a field and traction capacity of power means has been formulated and solved. The offered system of realization of optimum high-speed modes of movement of mobile machine-tractor units in which transmission of energy is carried out through the hook-on device of power means.
