| Abstract: |
| Objective To scientifically evaluate the storage life of 4 types and 80 kinds of nonmetal weak links in a type of missile. Methods The fast evaluation process of storage life was built by four working levels, namely, analysis, test, evaluation, and verification. By means of laboratory accelerated aging tests, weathering tests, contrast tests and experience datum analysis, the storage life was evaluated using 4 method, including quantitative evaluation based on the laboratory accelerated aging tests, quantitative evaluation based on the existing accelerated aging tests data, semi-quantitative evaluation based on the contrast tests and qualitative evaluation based on the experience datum analysis. Results The natural rubber 1161, the JZ101-67 High damping shock absorber, the natural rubber 1157 and the 221 Grease were taken as the examples for application of the 4 methods. And the evaluation results showed that the storage life of all 4 types of nonmetal weak links was more than 23 years. Conclusion All the 4 types of nonmetal weak links met the requirements of life extension project. |
