Review and analysis of methods for applying vibration in ploughing

The vibration of the working bodies of the plows is forced and spontaneous. Forced vibration requires a drive from an energy source, and spontaneous vibration occurs without a drive if the working bodies are fixed to the frame by means of spring elements. In this case, the oscillation is caused by the variable soil resistance. The vibration mode should be such that the impulse and shock action of the working body allows the tool to be torn off from the treated medium, in which the soil relaxes and decomposes into components capable of mutual displacement. The effectiveness of vibration is to reduce the traction resistance of the plow. When choosing the direction of vibrations, preference should be given to transverse or vertical vibrations, since in the longitudinal direction of vibrations, the vibration speed should be greater than the speed of the plow. Such a mode of oscillation can be provided only with forced oscillations and, therefore, with additional energy consumption. Forced vibrations with a vertical direction may be less intense, but still effective. They can be realized by replacing the support wheel of the plow with a roller in the form of a regular octahedron with an inscribed circle diameter of 0.75 m. Since these vibrations do not coincide with the direction of movement of the plow, the speed of vibration may be less than the speed of movement of the plowing unit; anyway, a positive effect will be achieved.
