Sealing reliability plays a very important role in the aviation field. This paper develops a new sealing reliability analysis method which can be applicable to most of the static seals. For the long-term using rubber seals, it will emerge stress relaxation which may lead to sealing failure. Therefore, a stress relaxation factor is need to be defined, which will analyze the sealing reliability considering...
Firstly, the wear between the lock ring and hook of a retractable undercarriagedoor lock machine under the action of the periodic load has been discussed. Secondly, the calculations based on the Acrhard model has been established to confirm the incremental wear gap in a given time. Thirdly, the analysis and calculation model of the wear reliability were given when the size parameters, load, material...
