| Abstract: |
| 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. |
