Аннотация
In this study, an engineering model was developed to predict the contact fatigue life through contact fatigue test using two-roller machine. DBR (Dark and Bright Ratio) method is used to quantify the failure rate of damaged surfaces of micro-pitting occurance. The variation of failure rates with number of cycles for different Hertzian pressures and rotiaional speeds is demonstrated. We proposed the new regression equation for predicting the contact fatigue life with the film parameter. It is shown that the fatigue life prediction curve by the proposed formula gives very high goodness of fit with the contact fatigue test results.
