摘　　要：目的科学评估某型导弹4类80种非金属薄弱环节的贮存寿命。方法建立由分析、试验、评估、验证等4个层次工作组成的贮存寿命快速评估流程。以实验室加速老化试验、自然环境试验、对比试验、经验数据分析为手段,按照基于实验室加速老化试验结果定量评估、基于已有加速老化试验数据定量评估、基于对比加速老化试验结果半定量评估、基于近似产品经验数据定性评估等4种方法开展了试验评估工作。结果以天然橡胶1161、JZ101-67高阻尼减振器、天然橡胶1157、特221润滑脂等4种非金属薄弱环节为4种方法应用示例,得出了4种非金属薄弱环节贮存寿命都大于23年的评估结果。结论 4种非金属薄弱环节多能满足延寿工程的要求。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 rubber1161,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.
