Abstract
The purpose. To raise efficiency and quality of separation of potato heap by theoretical substantiation of rational parameters of separator, proceeding from conditions of non-damaging tubers at their stroke interaction. Methods. Theoretical researches of stroke interaction were spent with application of substantive provisions of higher mathematics, theoretical mechanics, methods of formulation of programs for numerical calculations on the personal computer and construction of graphical dependences, and also analysis of the gained results. Results. Equivalent scheme of stroke interaction of a tuber of potato with elastic surface of reflecting transporter is developed. In view of quotient of recovery of speed of a tuber at impact analytical forms for determination of value, direction and speed of a tuber after impact are gained. It has enabled on the basis of application of principle of momentum at impact to gain analytical forms for determination of stroke impulse and force of impact of a tuber with elastic surface of reflecting transporter. Conclusions. New mathematical model of stroke interaction of a tuber of potato is built at separation of heap. On the basis of the gained theoretical results rational kinematic parameters of quality accomplishment of the specified process under condition of non-damaging tubers of potato are probed.

Key words: potato, tuber, separation of heap, stroke interaction, stroke impulse, equivalent scheme.
