| Abstract: |
| Objective To analyze the effectiveness of the method of accelerated test and the effectiveness of the test. Methods The theory of accelerated test and the Arrhenius model were used to analyze the principle and the method of the temperature test. The reasonability of the acceleration method and limit was judged according to the range of the activation energy. The temperature and temperature gradient of important location were introduced and compared by test results and expected ones to explain the feasibility of the accelerated method and prove the validity of the test. Results The method of accelerated test was effective when Ea varied from 0.675 eV to 1.3eV, and the upper limit, lower limit and accelerated factor of temperature were appropriate. The temperature measured at the measuring spot and the temperature gradient in important positions were close to the target result. Conclusion The AF and temperature limit of the accelerated temperature test are proved with good reason. Accelerating the temperature and stress could effectively and reasonably reduce the time and cost of test. |
