Focusing on the hardness, residual stress and inclusions, a simulation method is proposed to compute the fatigue strength of carburized gears. The simulation is based on the comparison of bending stress at every position of defects with material's strength. For the purpose of putting inclusions in the imaginary material for the computation, the distribution of the inclusions size is applied in the weibull distribution, based on the microscope observation. As a result of simulation, the fatigue strength distribution follows a normal distribution and have good correlation with the bending fatigue test result. Density of the large size inclusions influences fatigue strengths.
