| Abstract: |
| At present vibration excitement in reliability enhancement test is often generated by repetitive all-axis vibrator, versus that in traditional reliability test by electromagnetic vibrator. A simplified model describing the cumulative damage of product was built, and an analysis on the excitement characteristics of the two types of vibrator was carried out. The difference between them was also analyzed with help of a simulation test in MATLAB environment. The results showed that it is only when fixtures and installations on all-axis vibrators are reasonably designed according to vibration theory that the excitement characteristics of all-axis vibrator can be fully utilized. |
