Accelerated Life Model

Combined with the actual project, a grating ruler accelerated life test device is designed, which can simulate the actual loads, including temperature, humidity and speed stress. An accelerated life test scheme based on stepped stress loading is proposed, and 6 grating rulers are tested based on time-censored test method. An accelerated life model based on Weibull distribution used for evaluating the lifetime is established. Related experimental techniques also can be typical application cases for innovative practical teaching.

Model Approach

An accelerated life model is an important factor affecting the evaluation of test data. Avoiding the existent difficulties of treating mixed data and based on the grey theory with composite GM(1,1) model, approach is presented for treating fatigue data under constant stress amplitude accelerated life tests. Availability of the approach has indicated by an example.
