Reliability study of disengaging mechanism based on fault tree analysis

摘要

According to the principle of FTA, through analysis of the failure of missile when flight and maintenance, the disengaging mechanism fault tree is built. The FTA allows conducting the qualitative and quantitative analysis, finding out the weak link of the system. The results indicated that the fault tree could clearly find the most influential factor happens in the top incident, which provides the basis on the rural power grids trouble predicted and trouble prevention work.
