Abstract: In this study, a finite element routine was first used to calculate the static displacements and stresses under the maximum compression and tension loadings in the connecting rod of universal tractor (U650), which were then used for critical points evaluation. Fatigue analysis and longevity after a 1000000-cycle load, assessed through using of ANSYS software. Calculations based on fatigue life and accurate loading histories permit rod to be optimized for durability without the need for expensive and time-consuming testing of series of prototypes. According to this study, the critical point of the connecting rod of U650 is end of the shank and near piston pin hole (point 46). This point is critical point not only in tensional loading but also in compressive loading. The allowable number of cyclic loading on this part under fully reversed loading assumption is 10⁸ cycles that will be increased by decreasing amount of the stress concentration coefficient. The results obtained from the present study can be used to bring about modifications in the process of connecting rod manufacturing.
