Проаналізовано способи відокремлення качанів кукурудзи від стебел. Досліджено фізичні та механічні властивості кукурудзи. Розроблено математичну модель визначення зусиль для відокремлення качана. Виконано верифікацію моделі з використанням експериментальних даних. Встановлено, що хвильова математична модель дає більш точні результати. Розроблена математична модель може бути використана для розробки конструкції качановідокремлювальних апаратів кукурудзозбиральних машин.
There has been an increase in demand of corn in the world. This requires the use of high-performance agricultural machinery, including combine harvesters. However, corn harvesters have high grain losses and their apparatuses must be improved. The aim of the article is justification of corn picker operation by developing a mathematical model of the process of cobs separation in the complex combination several forces. To verify this model the results of the simulation were compared to experimental data. The wave theory has proved to be more accurate compared to the static model. The results of the theoretical researches of the methods of corn-cobs separation from stems are given and mathematical models are worked out. The technological process of corn-cobs separation fulfilled by the combination of different forces is considered, and the valuation of the resulting tension. The technological process of cobs separation is considered in combination of many forces, and making assessments of the resultant tension. Further research will be focused on the intensification of this process by the integration of stretching the stalk together with its twisting.
