Stress-strain modelling state and fatigue of the working body of the tillage unit for weed removal

Abstract

It is possible to increase the efficiency of crop cultivation technology through the using of multifunctional equipment for soil cultivation. The analysis of tillage equipment showed that the development of a multi-functional tillage unit capable of performing the main tillage with weed removal and a set of operations for pre-sowing tillage is relevant. To quickly adapt the soil cultivating unit to changing operating conditions, the method has been developed for regulating the angle of attack of the combing machine, the width of the capture unit and the angle of entry of the working body into the substrate [1]. A method for calculating the fatigue life of the working body of a tillage unit is proposed.
