The failure rate model of components with the number of load application as life parameter is developed in this paper. Taking static strength failure and fatigue failure as the backgrounds, the dynamic reliability models of components under random repeated load without strength degradation and those with strength degradation are derived, respectively. Then, the failure rate model of components with the number of load application as life parameter is derived without strength degradation and those with strength degradation are derived, respectively. The relationship between reliability and the number of load application, and that between failure rate and the number of load application are discussed in different cases. The result shows that even though when strength doesn't degenerate, both reliability and failure rate of components decrease as the number of load application increases, and the failure rate curve has the partial character of bathtub curve with early failure period and random failure period. When strength degenerates with the number of load application, the reliability of components decreases more obviously, and the failure rate curve of components is bathtub-shaped.Keywords-failure rate; reliability model; the number of load application; load-strength interference

Residual strength is one of the important properties of materials and is the basis for material fatigue life prediction. In this article, the residual strength of 18CrNiMo7-6, a commonly used material for wind power gears, is degraded with the load of fatigue load. According to the law of fatigue damage generation and development, a residual strength degradation model is proposed. According to the comparison between the test results and the model, the accuracy of the proposed model is high. When the number of loading/total number of cycles is close to 0.7, the residual intensity will change significantly. It is helpful to further study the reliability change of wind power gears under high cycle fatigue.
