| Abstract: |
| A new accelerated life prediction method was put forward by using the advantages of grey system theory to solve the inadequate data problem of constant temperature accelerated degradation testing. This method was based on the grey GM(1,1) model and Arrhenius equation. The judgment basis and room temperature storage life extrapolation method for accelerated degradation testing was put forward, which was successfully applied in data processing of accelerated degradation testing on triode. This extrapolation method was compared with curve fitting methods. The results showed that the Grey GM(1,1) model has better adaptability. |
