Connecting rods, fatigue analysis of universal tractor via finite element method by using ANSYS

At the present research the connecting rod of universal tractor (U650) was simulated using ANSYS software and with its fatigue analysis, longevity after a 1000000-cycle load, was assessed. The goal of the investigation was analyzing connecting rod behavior against repetitive loads for fatigue phenomena. The results not only save cost and time but also optimize design process. By sophisticated analysis, critical nodes which probability of crack growth is more were finding. Results show that the critical point of crack growth obtained with 26.793 Mpa. This point in both tensile and compression test shows critical attitude. With fully reversed loading condition, load fluctuation cycle is about 108 so that with less stress concentration factor, it could be increase. The results obtained from the present paper can be used to bring up modifications in connecting rod manufacturing.
