Nature of soil under the influence of strain wedge

Abstract

Analysis of the concept of development of the national tractor and agricultural machinery of Ukraine and foreign engineering shows an increase in loading techniques, crop losses, increase the cost of agricultural products. Based on the hypothesis of a wedge formation coherent soil compartment is made by bending a mathematical model for determining normal and shear stresses in the soil under the influence of the wedge. This article presents the solution of differential equations using numerical methods, methods of research of mechanical systems to the operation of their resistance, the use of the theory of stability of solutions of differential equations. The magnitude of the disturbing forces acting on the chisel tool in comparison with the weight of the power unit is small, so the study of differential equations is expedient to carry out the determination of asymptotic stability. The indicator determines the asymptotic stability of the system to return to the law of the undisturbed motion. Based on studies of the wedge formation of coherent soil compartment is made by bending a mathematical model for determining normal and shear stresses in the soil under the influence of the wedge
