| Abstract: |
| In this study，the heat aging test of O-ring was carried out using thermal stress and its storage life was predicted.Based on the characteristics of O-ring，elongation at break was selected as the key index of the aging process.According to elongation at break at different temperature， the activation energy was calculated and the storage life was predicted.The predicted storage lives of three kinds of O-rings were in good agreement with the test results from practical storage，indicating the method was effective. |
