Abstract:

The functional principle and failure analysis of a landing gear cabin door lock mechanism are researched in this paper. The fastening process is important for achieving the mission of the mechanism. There are two potential risks in the fastening process that may impact the stealthy performance of an aircraft: accidentally open errors and lock hook position errors. These two risks compete with each other. Competing failure models are established for the fastening process of the lock mechanism. The extreme model is used to describe accidentally open failures, while Brownian motion (BM) with non-linear drift and the Poisson process are adopted to model lock hook position error failures. The reliabilities for the lock mechanism are calculated at different working times. Results and conclusions are illustrated and provide helpful insight into the changes and degradation of the fastening process of the lock mechanism.
