| Popis: | A novel competing failure model considering intermission is established in this paper, which is appropriate for aircraft connecting-rod-type cabin door retraction mechanism. Poisson process, Archard wear model and failure functions are integrated to describe the catastrophic failure and degradation failure of the aircraft mechanism. Intermission is introduced in the novel competing failure model after considering the actual working condition and working factors. Based on the analysis of mechanism working principle and failure characteristics, a certain aircraft connecting-rod-type cabin door retraction mechanism is studied as an example. The case results indicate that this mechanism has an unusual degradation process. Besides, the novel competing failure model with intermission is effective in engineering project. |
