【Abstract】 D nonlinear analysis was performed for 498 connecting rod assembly by the Finite Element method. The analysis involved both the contact and the fatigue problems. PRETS179 elements were used to simulate the pretension load of bolts. The fatigue safety factors of the assembly were calculated with the calibrated Goodman method based on the yield condition of Von Mises and the distribution of fatigue safety factors was demonstrated in the contour curves. The calculated results show a good agreement with the real condition.更多还原
