TO THE DETERMINATION OF THE CALCULATIVE RESISTANCE TO THE FATIGUE OF THE WORKING BODIES OF AGRICULTURAL MACHINES
A method is proposed for determining the calculated fatigue resistance of the working bodies of agricultural tillage and feed-crushing machines, particularly effective for parts made of steel having differences in plasticity resource with equal strength parameters. The method is based on taking into ac- count changes in the energy absorption coefficient of steel under cyclic loading, determined depending on the received deformation curves of low-cycle or high- cycle fatigue. The calculated fatigue re- sistances according to the proposed met- hod do not require restrictions in the area of increased voltage amplitudes given in the regulatory documents.
