Research of the Vibration Movement of the Combined Machine Straightener in the Longitudinal-Vertical Plane

Abstract

In the article, a theoretical study of the vibration behavior of the combined machine leveler used in the preparation of land for planting, caused by the variation of the forces acting on it in the longitudinal-vertical plane as well as the results of experimental researches conducted on studying the influence of the angle of deviation of the parallelogram mechanisms with leveler to the horizon, the mean square deviation of the heights of unevenness on the field surface, and the level of soil compaction. Theoretical researches are based on the laws and rules of theoretical mechanics and the theory of vibrations, and experimental researches are based on UzDst 3412:2019 “Experiment agricultural technics. Machines and devices for depth tillaging the surface of soil. Programs and methods of experiments” was conducted on the basis of the regulatory document. In this case, it was found that the amplitude of vertical forced vibrations of the leveler has a minimum value due to the reduction and elimination of the effect of the forces acting on the parallelogram mechanisms with the combined machine leveler installed in the horizontal or close to it when working, and due to the reduction and elimination of the effect of the variability of the physical and mechanical properties of the soil.
