ABSTRACT: This study focuses on the prediction of the fatigue life of the traction arm on the New Holland TT75 tractor, which is used under difficult agricultural conditions in Chad. Using finite element simulations on ABAQUS/CAE 2017 and of analysis of the S-N curve for S235JR steel, we estimated the fatigue life under loads cyclic in traction. The equivalent stresses are calculated using Goodman’s equation and then compared to the experimental data extracted by PlotDigitizer. The linear Miner, nonlinear Tikri and Lemaitre-Chaboche damage cumul models are applied without overloads to evaluate fatigue strength and generate Gassner curves. The results highlight the sensitivity of the current arms and underscore the value of geometric optimizations.
