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.]]>Akinci, I., D. Yilmaz and M. Canakci,200512400404Artamonov, M.D., V.A. Ilarionov and M.M. Morin,19761st Edn.Bannantine, J., J. Comer and J.
