Dynamic Performance Analysis of Cage in Four-Point Contact Ball Bearing

open access: yesLubricants, 2022
Due to the special structure of double-half inner rings, four-point contact ball bearings are prone to uneven forces in the inner raceway during movement, which affects the dynamic performance of the rolling element and cage, and even leads to cage ...

A Generalized Bearing Dynamic with Adaptive Variation of Equation Numbers and Sliding Behavior Investigation

open access: yesLubricants, 2023
The complex sliding behavior inside ball bearings seriously affects the mechanical system’s performance. Current dynamic models for predicting this behavior suffer from poor generality and convergence.

Deep learning-enabled real-time personal handwriting electronic skin with dynamic thermoregulating ability

open access: yesnpj Flexible Electronics, 2022
The rapid rise of the Internet of things (IoT) have brought the progress of electronic skin (e-skin). E-skin is used to imitate or even surpass the functions of human skin. Thermoregulating is one of the crucial functions of human skin, it is significant

Research on the Bearing Sliding Loss Based on Time-Varying Contact Angle between Ball and Raceway

open access: yesLubricants, 2022
Based on the mechanical model, the friction loss between the ball and the raceway along the major axis of the contact ellipse is analyzed. The result shows that this part of the loss accounts for about 13.67% of the overall loss, which is mainly ...

A Study on Bearing Dynamic Features under the Condition of Multiball–Cage Collision

open access: yesLubricants, 2022
Cage stability directly affects the dynamic performance of rolling bearing, which, in turn, affects the operating state of rotating equipment. The random collision between the rolling elements and the cage pocket is the main reason for cage instability ...

Comparison-embedded evidence-CNN model for fuzzy assessment of wear severity using multi-dimensional surface images

open access: yesFriction, 2023
Wear topography is a significant indicator of tribological behavior for the inspection of machine health conditions. An intelligent in-suit wear assessment method for random topography is here proposed.

Precisely spun super rotors [PDF]

open access: yesNature Communications, 2021
AbstractImproved optical control of molecular quantum states promises new applications including chemistry in the quantum regime, precision tests of fundamental physics, and quantum information processing. While much work has sought to prepare ground state molecules, excited states are also of interest. Here, we demonstrate a broadband optical approach
