Abstract
The article presents the results of experimental studies of the ripping resistance force on a tracked bulldozer-ripper manufactured by the Chelyabinsk Tractor Plant. The experiment covers three ripping depths and eight angles. It has been experimentally established that the dependence of the ripping resistance force on each of these parameters is quadratic. The authors propose the use of a complex parameter which is equal to the product of the ripping depth by the angle when studying the ripping process. The use of the complex parameter for two-factor analysis allowed them to reduce the degree of the studied dependence while preserving the required accuracy. The complex parameter reflects the relationship between the design parameters of the ripper tooth, the ripping depth, and angle.
Highlights
Ripping is an integral part of the technological cycle both for agricultural and road building machines [1, 2]
The hinged systems of road building machines designed for the destruction of firm, frozen, and rocky soils are fundamentally different from the hinged systems of ripping machines
It has been established that the forces acting on the working tool in relation to the soil depend on the ripping process parameters: ripping depth h and the angle α
Summary
Ripping is an integral part of the technological cycle both for agricultural and road building machines [1, 2]. Systems with one-sided force closure do not provide positive penetration of the working tool into the soil or ensure its free movement relative to the tractor Such systems are typical for agricultural tillage machines. The hinged systems of road building machines designed for the destruction of firm, frozen, and rocky soils are fundamentally different from the hinged systems of ripping machines Their hinged systems ensure the positive penetration of the working tool into the soil. It has been established that the forces acting on the working tool in relation to the soil depend on the ripping process parameters: ripping depth h and the angle α At present, these dependences are mainly studied experimentally [7, 8]. Theoretical studies are reduced mainly to the models of a discrete element [9, 10, 11]
