Analysis and Application of Fault Tree Analysis in Crank Fracture Fault of
Certain Type Locking Mechanism of Projectile Hoist |
| |
| Abstract: | In order to effectively solve the problems of equipment, the fault tree analysis method is used to analyze the
crank fracture fault of the locker locking mechanism that appears in the commission. Find the cause of the failure, draw a
fault tree, and find out the logical relationship between the causes of the failure. Through qualitative analysis and
quantitative calculation, the minimum cut set of the fault tree is determined, the probability of occurrence of the top event
and the probability of occurrence of each cut set are calculated, and the influence degree of each cause fault is analyzed.
This research can provide a basis for efficient troubleshooting. |
