Legendre Multiwavelet Transform and Its Application in Bearing Fault Detection

Applied Sciences, 2023
Bearing failures often result from compound faults, where the characteristics of these compound faults span across multiple domains. To tackle the challenge of extracting features from compound faults, this paper proposes a novel fault detection method ...

Defect Size Evaluation of Cylindrical Roller Bearings with Compound Faults on the Inner and Outer Races

Mathematical Problems in Engineering, 2022
Faults in cylindrical roller bearings are one of the main contributors to major faults in rotating machinery. The development of bearing fault diagnosis technologies is key to measuring the performance, status, and risk of failure of rolling-element ...

Local Moment Instability of Os in Honeycomb Li2.15Os0.85O3. [PDF]

, 2018
Compounds with honeycomb structures occupied by strong spin orbit coupled (SOC) moments are considered to be candidate Kitaev quantum spin liquids. Here we present the first example of Os on a honeycomb structure, Li2.15(3)Os0.85(3)O3 (C2/c, a = 5.09 Å ...

Intelligent Diagnosis of Rolling Bearings Fault Based on Multisignal Fusion and MTF-ResNet

Sensors, 2023
Existing diagnosis methods for bearing faults often neglect the temporal correlation of signals, resulting in easy loss of crucial information. Moreover, these methods struggle to adapt to complex working conditions for bearing fault feature extraction ...

Structural Properties, Order-Disorder Phenomena and Phase Stability of Orotic Acid Crystal Forms [PDF]

, 2016
Orotic acid (OTA) is reported to exist in the anhydrous (AH), monohydrate (Hy1) and dimethylsulfoxide monosolvate (SDMSO) forms. In this study we investigate the (de)hydration/desolvation behavior, aiming at an understanding of the elusive structural ...

A Compound Fault Labeling and Diagnosis Method Based on Flight Data and BIT Record of UAV

Applied Sciences, 2021
In the process of Unmanned Aerial Vehicle (UAV) flight testing, plenty of compound faults exist, which could be composed of concurrent single faults or over-limit states alarmed by Built-In-Test (BIT) equipment.
