Reliability analysis of excavator boom considering mixed uncertain variables

Abstract: There are differences among sampling data and representation types of uncertain interval, fuzzy and random variables, which increases the complexity of structure reliability analysis. A α, β‐Cut‐FORM is proposed to analyze structure reliability considering the mixed uncertain variables. Fuzzy variables are optimized on the interval under two cut sets (α, β) based on the theory of cut set optimization. Interval variables are modeled with probability using a uniformity method. The proposed method involves the ne… Show more

“…Through the direct integration of the sensitivity reliability model, the accurate first-order and quasi-failure probability sensitivity index of mechanical structure under dynamic excitation can be obtained. [30][31][32][33] Jensen 34 proposed a simple post-processing step associated with an advanced sampling-based reliability analysis to quantify the impact of individual input variable on the output parameter, which also validated on two nonlinear structural models under stochastic ground excitation. Zhu 35 studied a response surface function Kriging model with Sobol' sensitivity algorithm.…”

“…Logically, these methods are constructed based on the game/balance between stress and strength. A system or a structure would be safe, free from failure, and reliable when the strength is larger than stress, from both localization's and globalization's points of view 23,24 . Otherwise, failures and accidents would happen due to low reliability.…”
