中文摘要:
      目的 对某型橡胶减振器进行加速老化试验研究,利用试验数据评估得到产品的贮存寿命。方法 采用恒定应力加速试验方法,分四个温度应力量级,对橡胶减振器的压缩永久变形试样开展加速老化试验,获得试样的退化数据。对试验数据进行分析计算,评估得到橡胶减振器材料的贮存寿命。结果 通过评估,得到该型减振器材料的贮存寿命能够达到12.36年,置信度大于0.99。同时利用减振器真实产品的老化试验验证了寿命评估结果。结论 以温度为敏感应力,采用恒定应力加速贮存试验方法,可以在短时间内快速获得置信度较高的材料常温贮存寿命,结合真实产品验证评估结果,为类似产品的寿命预测提供支撑。
英文摘要:
      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.
