| Abstract: |
| The paper aims to stimulate weak links of aviation packing box. Based on potential failure mechanism and the life profile, an accelerated testing which gave overall consideration to damp heat test, random vibration test, fork transport test, artificial dismounting test, impact test and drop test was designed by time compression, events compression and accelerating stress method. The test time was shortened to 96 days to stimulate 16 years working life of packing box. The potential failures such as metal corrosion and structure damage were stimulated successfully. Furthermore, the reliability level of packing box was improved by improvement measures. The results show that this method is reasonable and feasible to design accelerated testing under multiple environmental stresses. |
