Information × Registration Number 0207U000912, 0104U003797 , R & D reports Title Development of the beet harvesters working processes theory. popup.stage_title Head Volodymyr Bulgakov, Registration Date 22-02-2007 Organization Scientific research institute engineering and technologies NAU of Ukraine. popup.description2 The purpose - creation of new theories of beet pullers working processes which will allow to use optimum kinematic and design parameters of end-effectors at a stage of its projection. Method of research - theoretical, mathematical simulation of beet pullers working processes by compiling sets of the differential equations of motion. The new interaction theory of the flexible cleaning vane with a root crop head surface in a field during its cleaning from haulm residues is developed. The new theory of sugar beet root crops digging up from soil by share lifter is developed. The new theory of the forced longitudinal oscillations of a root crop fixed in soil, and also the theory of root crop extraction out from soil by a vibrational digging out end-effector are developed. Application of the outcomes of researches to production of the new constructions of haulm gatherers and beet pullers is made at the factory of agricultural machine industry.
