| Abstract: |
| Objective The accelerated storage test was designed for a type of rubber ring seal and the life of storage was predicted through the test. Methods Based on the failure mechanism of the rubber ring seal in storage environment, combined with the aging model of rubber material, on the premise of neither changing the failure mechanism nor adding new failure mechanism, the rubber ring seal was chosen as the test object, the test method of putting more stress to accelerate the process of product failure was used, and the life of storage in the normal environment was predicted according to the test result. Results The design and validation of rubber ring seal storage accelerated test were carried out with the temperature stress as accelerated storage stress. When the storage temperature in the environment was 20 ℃, the life of storage could reach 16.97 years, and the confidence was greater than 0.95. Conclusion The storage accelerated test was conducted with the whole rubber ring seal as the test object and the temperature stress as the storage sensitive stress, the estimated storage life was in relatively good accordance with the natural storage life result of the product, and the test status was much more real. It provided the reference for the replacement period of rubber ring seal. Meanwhile, it provided a method for quantitative evaluation of the storage life of the rubber ring seal. |
