| Abstract: |
| Objective To research accelerated storage of certain antenna, utilize the experimentation data to assess life and obtain accelerated factor of product. Methods A step-down-stress storage testing was designed for twelve products to obtain degenerated records. Two accelerating models were used to deal with these dates, and then contrast to make sure the most valuable technique. Results The activation energy of product could be obtained through acceleration model assessment based on drift Brownian movement. Then, the accelerated factor and storage life could be calculated. Conclusion The step-down-stress storage method can speed up the accumulation of product damage. It is convenient to obtain data of degeneration quickly. The evaluation based on drift Brownian movement provides a new reference for assessment of the antenna. |
