A temperature rise calculation model of wind turbine gearbox gear considering crack fault and tooth number difference

IET Renewable Power Generation, Volume 18, Issue 15, Page 3416-3428, 16 November 2024.
A temperature rise calculation model of wind turbine gearbox gear considering crack fault and tooth number difference is proposed. The data of high‐speed gear of a wind turbine gearbox in northern China is selected for simulation verification. By comparing with the finite element method, the effectiveness of this method is verified.

Tribological properties of real foods using extended Stribeck curves and their relationship with nutritional and rheological parameters

Journal of Texture Studies, Volume 55, Issue 4, August 2024.
Tribological properties of 19 commercial food products in 6 categories (yogurts, dressings, spreads, porridges, emulsified sauces, and syrups) were investigated. The extended Stribeck curves across the four frictional regimes (the static, boundary, mixed, and hydrodynamic regimes) varied depending on the flow behavior, nutritional compositions, and the

Large‐Scale Numerical Simulation of the Solid Lubricant Behavior in the Leg Joints of Insects

Advanced Theory and Simulations, Volume 7, Issue 6, June 2024.
Semi‐solid lubricant in the insect legs joints is represented by cylindrical fragments with a diameter of ≈1 µm. The results of numerical simulation show that the fragments tend to adhesion and the formation of clumps of different shapes and sizes. Such a system allows maintaining clearance between surfaces while reducing friction and elimination of ...
