Theoretical probe of movement of end-effectors wide-track power machines

Abstract

The purpose. Elaboration of mathematical dependences determining acceptable limits of cross-section offsets of end-effectors of specialized wide-track agricultural machines, and justifying area of protected zone proceeding from absence of damageability of plants. Methods. Original positions of theoretical mechanics, theory of probability, creation of programs and calculations on PC. Results. New mathematical dependences determining acceptable limits of cross-section offsets of end-effectors, which are characterized by root-mean-square aberration of agrotechnical conditions according to damageability of plants in a row are developed. Such situation often occurs at general assessment of indexes of operation wide-track agricultural machines in track system of farming agriculture. Conclusions. At arrangement of end-effectors of cultivator for wide-track agricultural machines it is necessary to consider the factor of variance of their offsets. For the end-effectors which are outside concerning geometrical axis of a row and center of agricultural machine, the value of protection zone should be greater than for inner, under condition of uniform damage of plants in a row (approximately for 3 cm).
