| Abstract: |
| To study on compiling method of atmospheric corrosion and dynamic fatigue co-loading environment & load test spectrum for materiel key structure. The synergistic-action characteristics of corrosion environment and fatigue stresses were analyzed according to the materiel structure life-environment profile in service. The design principle and compilation methods of corrosion-fatigue environment & load spectrum for materiel structure were concluded. Synergisticand accelerated test spectrum of corrosion environment-fatigue load for certain materiel structure was established using the environment & load spectrum compilation methods. The established environment & load spectrum compilation methods and accelerated test spectrum of corrosion-fatigue synergistic-action could be utilized to study on corrosion-fatigue synergistic environmental effect and accelerated testing evaluation methods for materiel key structure and so on. |
