An Ultrahigh Power Density and Ultralow Wear GaN‐Based Tribovoltaic Nanogenerator for Sliding Ball Bearing as Self‐Powered Wireless Sensor Node

Advances in Materials, 2023
The tribovoltaic effect is regarded as a newly discovered semiconductor effect for mechanical‐to‐electrical energy conversion. However, tribovoltaic nanogenerators (TVNGs) are widely limited by low output power and poor wear resistance for device ...

Research on the vibration characteristics of the ball bearing considering the uncertain bearing-shaft interference fit

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2023
Due to the exist of the inevitable dimensional tolerance and assembling errors in the ball bearing, the interference amounts between the inner ring and the connected shaft are uncertain but bounded, which could directly affect the dynamics performance of

Effect of thermal elastohydrodynamic lubrication on vibration characteristics of ball bearing with local defect

Proceedings of the Institution of Mechanical Engineers, Part K: Journal of Multi-body Dynamics, 2022
The vibration response of ball bearing with local defect is closely associated with its lubrication condition. The previous bearing dynamic models were mainly established based on the idealised lubrication conditions, which may not uncover the influence ...
