Strain, Volume 59, Issue 6, December 2023., 2023 Abstract Precise determination of the remaining service life of technical components requires sufficient knowledge of fatigue crack growth behaviour and the growth rate of defects. Cracks in real components often experience multiaxial far field stresses due to their complex geometry and composite loadings acting on it.

Bearing Early Fault Diagnosis Based on an Improved Multiscale Permutation Entropy and SVM
Shock and Vibration, Volume 2022, Issue 1, 2022., 2022 Bearing fault is a process of gradual development and deepening. In the early stage of the fault, if it can be found out in time and taken reasonable prevention and elimination measures, we can avoid serious losses and safety accidents. Therefore, the feature extraction and analysis of early weak fault has important practical significance.

Step‐by‐Step Penalized Blind Kriging Methods for Surrogate Modeling
Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022 When building a surrogate model, it is important to identify a proper mean function for the kriging model. The commonly used variable selection method is the penalized blind kriging (PBK) method. But this method could lead to a low time efficiency, which is not suitable for experiments with time‐sensitive data.

Dynamic Characteristics Analysis of 3D Blade Tip Clearance for Turbine Blades with Typical Cracks
International Journal of Aerospace Engineering, Volume 2022, Issue 1, 2022., 2022 As well known, the crack is a typical fault of turbine blades, which is difficult to detect due to the weak fault features contained in the rotor vibration. Although some fault diagnosis methods based on blade tip timing (BTT) are proposed to detect blade cracks, the limited fault features can be extracted because the BTT signals contain only one ...

Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021 Taking the traction motor of CRH2 high‐speed train as the research object, this paper proposes a diagnosis method based on random forest and XGBoost for the compound fault resulting from stator interturn short circuit and air gap eccentricity. First, the U‐phase and V‐phase currents are used as fault diagnosis signal and then the Savitzky–Golay ...
