Mathematical model of vibration digging up of root crops from soil = Математична модель вібраційного викопування коренеплодів із ґрунту

The reason for large-scale use of vibrational digging tools in root harvesters of the modern technical level is their significantly lower draught level, actual ability to dig up beetroots from the soil without damage and losses. Oscillations of the digging tool create conditions, under which the soil that adheres to roots is intensely beaten down when they are dug up, which facilitates high level of qualitative indicators. That’s why development of new constructions of vibrational digging tools, as well as research of their operation for the purpose of determination of the optimal constructive and kinematic parameters is a current task of the branch of mechanisation of sugar beet growing (Sarec et al., 2009; Lammers, 2011). Statement of the problem. Analytical research of the process of interaction between working elements of the vibration digging tool with the root, that allows to obtain kinematic, constructive and technological parameters, and gives the opportunity to determine their optimal value.
