METHOD OF REASONING OF THE CONSTRUCTION SCHEME OF MULTIPLE LAPP ON THE BASIS OF THE BIOLOGICAL PROTOTYPES

Abstract

Crop growing technologies have a steady tendency to improvement, which requires the same constant adaptation of the machine system to the operating conditions. Changes in technology are almost always accompanied by changes in the tillage system.Among the last essential innovations it is necessary to note the system of organic farming. A characteristic feature medium becomes of its introduction is the presence in the surface layer of the soil of a significant amount of plant residues that have not completely passed the stage of humification. As a result, the degree of soil consolidation is reduced. At the same time, the main tillage implements are designed for work in the conditions of retaining cutting and their use in conditions of reduced consolidation of the processed problematic. As a solution to the problem, we propose to improve the streamlining of the working surfaces and the cutting perimeter based on the use of bionics methods. In particular, by borrowing the body shape of marine animals with good hydrodynamic properties.The purpose of this study is to substantiate by the methods of bionics the design parameters of the lancet paw, adapted to work in organic farming.In this paper, we have proposed a method for substantiating the constructive schema of the arched lapi on the basis of an analysis of the body of a biological prototype - the California sea stingray. An example of a specific calculation of the cutting perimeter profile is given, the basic dimensions of which correspond to the dimensions of a technical prototype.The studies conducted allowed us to draw the following conclusions: the proposed method allows to obtain the regression equation of the profile of the cutting perimeter of the working body, which allows to develop a mathematical model of its interaction with the treated environment. The presence of such a model in combination with the soil model, makes it possible to adapt the profile to work in soil conditions.
