Annotation

A promising direction for further development of agriculture not only in Ukraine but also in the world is the introduction of innovative technologies, to which we should include the track system of agriculture. The movement of transport and energy vehicles on the aligned compacted trace of the constant technological track causes undesirable and uncharacteristic vibrations for agricultural machinery. The latter are due to the influence of the microprofile of the constant technological track, which has a significant negative impact on the degree of comfort and efficiency of the operator, operational and technological indicators, reliability and smoothness of machines. The method and results of experimental automated estimation of the microprofile of irregularities of traces of the constant technological track are presented in the article. Experimental studies of the microprofile of irregularities of the traces of the constant technological track have shown that the standard deviation of the irregularities of the profile is ± 0.84
According to their internal structure, the inequalities of the profile of traces of the constant technological track are characterized by a function that contains, along with random components, the harmonic ones, which are expressed by attenuating periodic oscillations of the normalized correlation function. The main share of variances of oscillations of the irregularities of the profile of the traces of the technological track is concentrated in the frequency range from  0… 0.3 cm − 1. The generator of formation of irregularities of a longitudinal profile of soil traces of a constant technological track are parameters of ground hooks of tires of wheels of the cars moving on it.This is confirmed by the fact that the length of the correlation of the ordinates of the irregularities of the profile of the traces of a constant technological track in the conditions of tests of the bridge agricultural tool of the new design is about 0.18 m, which corresponds to the pitch of its tires.

Keywords: constant technological track, vibration, microprofile, methodology, profile of inequalities, automated profilograph, experimental researches
