MATHEMATICAL MODEL OF A ARTICULATED FRAME WITH A CAB TURN MECHANISM

Abstract

Tractors are technological energy means used for general mechanization and automation of agricultural production, as well as for the transportation of finished raw materials. Tractors of traction class 8 must have high productivity and efficiency, in order to achieve the best results, in the shortest agrotechnical time. The need for the development of tractor designs of the 8th traction class is explained by current trends in the development of agriculture. The increase in the area of agricultural land sets manufacturers the task of increasing the speed of tillage, which entails an increase in the power and ergonomics of tractors. The necessary traction and layout characteristics of energy-saturated tractors of traction class 8 allow the implementation of articulated frames. The main task of the design is the development of a articulated frame with a cab rotation mechanism that will be able to fulfill the requirements for modern tractors of the 8th traction class. Purpose. Investigation of the forces of resistance to rotation of the articulated frame and the occurrence of a favorable moment for turning the cab using a model in the MATLAB Simulink environment. Methodology. Methods of mathematical modeling and analysis were used in the article. Results. The parameters showing the necessary forces for the rotation of the articulated frame and the occurrence of a favorable moment for turning the cab are obtained. Practical implications. The results obtained can be applied in the design of a tractor on a articulated frame with a cab rotation mechanism.
