Intelligent acoustic-based fault diagnosis of roller bearings using a deep graph convolutional network

, 2020
Roller bearings form key components in many machines and, as such, their health status can directly influence the operation of the entire machine. Acoustic signals collected from roller bearings contain information on their health status. Hence, acoustic-

Numerical simulation of particle flow and segregation during roller spreading process in additive manufacturing

Powder Technology, 2020
Additive Manufacturing (AM) using powder spreading requires uniform spreading. For narrow spreader gaps, as commonly used, transient jamming and segregation could adversely affect the uniformity of the spread layer.

Development and testing of rolling cutter bit with a new arrangement of teeth on the balls

Известия высших учебных заведений: Нефть и газ, 2020
Research has found that the axial load applied to the bit is distributed unevenly along the crowns of the balls. The middle crowns are the busiest.
