Self‐Powered Bearing Sensing and Real‐Time Fault Diagnosis Enabled by Non‐Invasive Triboelectric Sensors and Edge AI Acceleration

Advanced Science, EarlyView.
This study achieves the synergistic integration of self‐powered sensing and edge AI acceleration to establish a real‐time fault diagnosis system. The proposed TENG‐based self‐powered bearing sensor (NSE‐TBS) and FPGA‐accelerated edge AI framework fundamentally break through the inherent limitations of conventional monitoring systems, including complex ...

ROLLING CONTACT FATIGUE PERFORMANCE OF SELECTIVE LASER MELTED TI-6AL-4V

Jixie qiangdu, 2019
Selective Laser Melting（ SLM） can directly fabricate parts that are difficult or time-consuming for processing or even can not be processed in traditional way. And SLM is one of most promising addictive manufacturing techniques.

Electrostatic Self‐Assembly Induced Nest‐Like MXene Networks on Fabric for Ultra‐Broadband Flexible Absorption

Advanced Science, EarlyView.
In this study, an electrostatically self‐assembled WPU‐MXene@FC flexible fabric constructs a “nest‐like” structure on fibers, building construct MXene multiple loss paths, achieving ultra‐wideband absorption of 25.3–1200 GHz in a thickness of 1.8 mm, while also exhibiting superhydrophobicity, acid and alkali resistance, and bending resistance ...

Study on Relationship between Contact Stress Distribution Characteristic and Fatigue Spalling of Angular Contact Ball Bearing at High Speed

Jixie chuandong, 2021
Fatigue spalling is one of the main failure forms of bearing， and the change of contact stress between rolling body and raceway is an important factor causing fatigue spalling of bearing.

Residual Stress in Wheels: Comparison of Neutron Diffraction and Ultrasonic Methods, with Trends in RCF

, 2014
The critical damage mechanism on many GB passenger train wheels is Rolling Contact Fatigue (RCF) cracking in the rim. Evidence from field observations suggests that RCF damage occurs much more quickly as the wheelsets near the end of their life.

Plastic deformation of rough rolling contact: An experimental and numerical investigation [PDF]

, 2014
Quantifying the surface roughness evolution in contacts is a crucial step in the fatigue prediction process. Surfaces are initially conditioned by the running-in process and later altered by surface fatigue.
