The article considers the experience of involving bionics methods in the development of tillage tools. The essence is as follows. The basis is the existing working body, which performs the technological process to be modernized. Based on the analysis of the body structure of marine animals, a biological analogue is selected, which has the largest number of elements of identification with the prototype. A geometric and numerical model of the animal's body is created. Based on the numerical model, a mathematical regression model of the geometry of the future working body is developed. The next step on the basis of the regression model is a mathematical model of the interaction of the working body with the soil environment. The mathematical model allows to analyze the process of interaction with the soil environment of the individual components of the cutting perimeter, which serves as a basis for adjusting the design parameters of the site and the tool as a whole. The paper proves that the shape of the body of the sea stingray can almost perfectly serve as a biological analogue of tillage implements, both for deep and surface tillage. A method of joint use of two or more biological analogues is proposed. in the case of the development of a combined tool. Product Description popup.authors Konovyi Anatolii V. Krotiuk Diana P.
