Active Kriging-Based Adaptive Importance Sampling for Reliability and燬ensitivity Analyses of Stator Blade Regulator

Abstract: The reliability and sensitivity analyses of stator blade regulator usually involve complex characteristics like highnonlinearity, multi-failure regions, and small failure probability, which brings in unacceptable computing efficiency and accuracy of the current analysis methods. In this case, by fitting the implicit limit state function (LSF) with active Kriging (AK) model and reducing candidate sample pool with adaptive importance sampling (AIS), a novel AK-AIS method is proposed. Herein, the AK model and Mar… Show more

“…As one valuable computing method, surrogate modeling methods have emerged and attracted much attention in reliability design fields [54][55][56][57]. In the surrogate modeling method, the tremendous computing tasks of real limit state functions can be avoided by establishing a surrogate mathematical model, which is conducive to alleviating the computing burdens and improving the computing efficiency [58][59][60]. For instance, Meng et al [61] proposed an enhanced collaborative optimization method based on the adaptive surrogate model for the design of high-dimensional nonlinearity systems.…”

“…For example, Zaidel et al proposed a neuromorphic algorithm based on nef for inverse kinematics and PID control in order to improve the motion accuracy of the 6-DOF robotic arm (Zaidel et al, 2021). In addition, in order to improve the motion accuracy and stability of the mechanism, Zhang's team not only proposed a new sampling method based on active Kriging model and adaptive importance sampling, but also proposed a multistage linkage method based on active extreme value Kriging (Zhang et al, 2022;Zhang et al, 2023). In recent years, with the continuous development of artificial intelligence technology, artificial intelligence technology has been widely used in various fields.…”

“…Combining adaptive learning strategies with surrogate models, that is adaptive surrogate-model-based reliability evaluation is one of the ways to solve the above problems in reliability analysis field. A lot of valuable researches have performed on adaptive surrogate-model-based reliability evaluation method (Echard et al ., 2011; Marelli and Sudret, 2018; Luo et al ., 2022b; Yu et al ., 2022; Yu and Li, 2021; Meng et al ., 2015; Zhang et al ., 2022a, 2022b; Deng et al ., 2022).
