As demonstrated in Fig. five, the remaining aspect displays the variance-based sensitivity end result at the takeoff stage, As well as in the ideal facet is The end result in the landing stage. It might be noticed that the worldwide sensitivity index varies With all the have on situations, and the global sensitivity ranking may well alter in various dress in situations. Once the dress in periods is less than 40000, based on the variance-based sensitivity ucuz uçak bileti, en uygun uçak bileti index, the value of the worn roller wheels could be ranked in the descending order as Δr2, Δr4, Δr6, Δr8, Δr10, Δr12. Even so, the position will become Δr6, Δr2, Δr4, Δr8, Δr12 Δr10 once the put on times reaches 60000. Total, it is clear the roller wheels selected as r2, r4, r6 tend to be more significant than The remainder.
The two unique failure threshold values and different wear occasions have an important effect on the failure chance. Thus, the failure threshold value is fixed as 0.8 to calculate the failure probability primarily based sensitivity index in different put on instances and The end result is revealed in Fig. 6. Notice that we only clearly show the sensitivity index outcomes of roller wheels all through 50000 to 51000 dress in periods. Then, the amount of use times is preset at 50000 to calculate the failure likelihood centered sensitivity index in different failure threshold values, and the result is revealed in Fig. seven.
As is usually found from Fig. 6, in accordance with the success of the variance-based sensitivity index, the relevance ranking from the worn roller wheels may be rated in the descending buy as Δr2, Δr6, Δr4, Δr8, Δr10, Δr12. As well as in Fig. 7, the failure likelihood dependent sensitivity index of all six roller wheels first raises after which decreases in the event the failure threshold benefit improves from 0 to one.two. On the other hand, the global sensitivity position would not transform substantially.
Now let us have a brief evaluation in the reliability Investigation brings about Fig. four and the worldwide sensitivity Examination leads to Fig. five, Fig. six, Fig. 7. Based on the brings about Fig. 4, the failure likelihood of slat system little by little decreases Together with the failure threshold worth boosts. Therefore, it’s important to select an inexpensive failure threshold worth based on the demand from customers for the output efficiency from the slat mechanism in the process of trustworthiness analysis. In keeping with Fig. 5, Fig. 6, Fig. seven, sensitivity indices of Δr2, Δr4 and Δr6 are naturally more substantial as opposed to Other people. It means that the roller wheel specified as r2, r4 and r6 have the obvious impact on the motion dependability and robustness of your slat mechanism. The Assessment signifies that All those roller wheels tied with increased sensitivity needs to be paid out additional interest to given that the assistance in the plane proceeds, and proper servicing or perhaps alternative is essential at important time. From the above Evaluation, it can be witnessed that the global sensitivity index does provide far more underlying information and facts for us. Conclusions
