The purpose of the work - to create a new construction of a vibrational digging out end-effector on the basis of the new theory which will allow to use at a design stage of end-effectors their optimum kinematic and design parameters. Method of research - theoretical, mathematical simulation of vibrational digging up working process, by compiling sets of the differential equations, and also experimental. The new theory of longitudinal oscillations of the fixed in soil sugar beet root crop which arise owing to operation of a vibrational digging out end-effector is developed. The variational principle of Остроградского-Hamilton is applied. The mathematical model of sugar beet root crops vibrational digging up is developed. The new construction of a universal vibrational digging out end-effector for a sugar beet and other root crops is developed, its laboratory and field trials are executed.
