Abstract

The theory of the force action of the working body of the slitter on the ground is considered. It is proposed to divide this force into four components: the force of cutting the material, the force of overcoming the friction forces acting on the ground, the force of cracking the material and the force of resistance of the ground environment. Theoretical dependences for determining the components of the tool’s traction resistance when using vibration are proposed. As a result of theoretical and experimental studies, it was found that due to the vibration effect of the working body of the slot rod, the traction resistance is reduced by 13.8%. The decrease is due to changes in the physical and mechanical properties of the soil under the influence of directional vibrations.

Highlights

Since the invention of the plow, the problem of determining the force required for its traction has arisen
The friction force of the soil on the front of the working body is determined by the formula
The friction force of the soil against the side wall of the working body due to the effect of "jamming" from the force Fz can be determined by the formula

Summary

Introduction

Since the invention of the plow, the problem of determining the force required for its traction has arisen. Given the direction of stress action in the cut element, we can present equation (4) in this form σ=x σ=z σb kдин Having solved each equation of the system (3), we determine the relative deformation of the cut element in the direction of the XYZ axes.
