| 目的 针对橡胶减振结构寿命试验时间较长，寿命预测困难的问题，建立了力-热双应力情况下的橡胶减振结构加速试验方法，并给出寿命预测模型。方法 首先，分析影响橡胶减振结构寿命的主要因素，建立典型橡胶减振结构的双应力加速试验方法，并开展加速退化试验。基于加速退化试验获得的试验数据，采用广义艾林模型作为双应力加速模型，Weibull分布作为寿命模型，建立了减振结构的双应力加速退化试验数据的分析方法。结果 预测了使用温度为25 ℃，压缩率为5%情况下，在给定可靠度0.9987时，减振结构贮存寿命约为9 a。结论 所建立的方法能够较好地预测减振结构的使用寿命。 |

| In order to solve the problem of long life test time of rubber vibration damping structure, firstly, the main factors affecting the life of vibration damping structure are identified, then the mechanical-thermal double stress accelerated test method of the typical vibration damping structure is construction, and the accelerated degradation test scheme is proposed. Based on the data obtaining from the accelerated degradation test, a data analysis method for the double stress accelerated degradation test of vibration damping structures is established. In this paper, the generalized Eyring model and Weibull distribution are chosen as the double stress accelerated model and life model, respectively. Based on the proposed method, the storage life of the vibration absorption structure with temperature of 25 ℃ and compression rate of 5% is predicted to be about 9 years when the given reliability is 0.9987. The proposed method can effectively predict the operating life of the vibration-damping structure. |
