Research on Dynamic Characteristics of Electromechanical Coupling for the Ultra‐Compact Wind Turbines

open access: yesWind Energy, Volume 29, Issue 9, September 2026.
ABSTRACT With the development of ultra‐compact wind turbines, the electromechanical coupling dynamic characteristics of integrated gearbox‐generator systems in their drive trains have attracted increasing attention. To reveal these characteristics, an electromechanical coupling dynamic model is established using the lumped parameter method and the ...

Characterizing Incoming Cocos Plate Structure Outboard of the Guerrero Gap and Adjacent Segments Offshore Mexico: Implications for Along‐Strike Variations in Megathrust Slip Behavior

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract Megathrust slip behavior in subduction zones can vary along‐strike, yet the mechanisms driving this variability remain uncertain. The Middle America trench offshore Mexico provides an ideal setting to investigate the structural controls on megathrust slip behavior.

On the Mutual Relation Between Contact Ratio and Crack Propagation in the Tooth Root of Spur Gears

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 9, Page 3896-3908, September 2026.
ABSTRACT This work investigates the mutual relationship between contact ratio and tooth root crack propagation in spur gears, with particular focus on the influence of meshing stiffness and load sharing on the tooth root lifetime. An experimental case study originally reported by Rettig, in which SN curves of gears with similar geometry but different ...
