| Abstract: |
| Objective To design the accelerated storage test for some rubber vibration isolator and get the storage life of product by evaluating experiment data. Methods The constant stress accelerated storage testing with four temperature stresses were carried out to have accelerating aging test for compression set sample of rubber vibration isolator. By analyzing and calculating the degeneration data, the storage life of materials for the rubber vibration isolator was evaluated and obtained. Results By evaluating, the storage life of materials for the rubber vibration isolator would reach 12.36 years. The confidence level could reach at least 0.99. Meanwhile, the aging test of real products of shock absorber verified the result of life assessment. Conclusion The constant stress accelerated storage testing with temperature as the sensitive stress can speed up the process of product failure and accelerate to obtain storage life with high confidence level. It could provide support for life prediction of similar products in combination with verification and evaluation result of real product. |
