“…The initial wear is related to the material properties of the bearings themselves, while the wear gradually slows down after entering the sTa wear stage [67,68]. In the later stages of wear, the bearing may undergo severe plastic deformation due to factors such as abrasive particles, changes in load, and other particles, which can accelerate the failure or damage of the bearing [69,70]. Figure 5 shows the percentage of factors affecting the wear loss efficiency of wind power bearings.…”

With the significant penetration of wind generation, wind turbines require higher and higher lubrication performance for bearings. To improve the lubrication performance of wind power bearings, this study takes wind power bearings as the research object and comprehensively analyzes the wear forms of wind power bearings as well as intelligent lubrication methods. Firstly, the main roles and wear forms of wind turbine bearings are sorted out and analyzed. Secondly, the common lubrication problems of wind power bearings are analyzed from the bearing grease selection, lubrication mode, and lubrication status, highlighting the important influence of lubrication on bearings. Thirdly, the wind turbine bearing wisdom lubrication method research and organization, mainly including the wind power generation bearing lubrication materials, lubrication devices and monitoring methods, and other issues of research and analysis. Finally, current challenges and future development directions are summarized, which are designed to provide theoretical reference and technical support for the related research and engineering practice in the field of wind power engineering.

“…As elastic state can go to plastic state under external loading through a transition state; thus, it has been shown [14, 18, 19, 22–29] that the asymptotic solution through principal stress leads from elastic state to plastic state at transition point P → ± ∞ . To determine the plastic stresses at the transition point P → ± ∞, we define the transition function Γ in terms of τ rr as:

Γ = 3 - 2 α_{3} - (\frac{2}{c_{33}}) (τ_{r r} + β_{1} Θ) = η^{2} [{((), P + 1)}^{2} + 1 (1 - α_{3})],

where Γ is a transition function of r and α 3 = 1‒( c 13 / c 33 ).…”

This article deals with the study of thermal stress in a hemispherical shell made of transversely isotropic material under the effect of thermal, pressure and mechanical load. Seth's transition theory and generalized strain measure are used for finding the governing equation. Mathematical modelling is based on stress–strain relation and equilibrium equation. Analytical solutions are presented for the hemispherical shell made of transversely isotropic material and isotropic material. The effects of different pertinent parameters (i.e., temperature, pressure and load) are considered for the spherical shell made of transversely isotropic material. The behaviour of stress distribution, mechanical load, pressure rise, and temperature distribution are investigated. From the obtained results, it is noticed that carbon fiber material hemispherical shell requires higher pressure at the internal surface in comparison to magnesium/polypropylene material. With the introduction of mechanical load, the value of pressure decreases at the internal surface, but reverse results are obtained in the case of thermal condition for the hemispherical shell made of carbon fiber/magnesium/polypropylene material. By applying thermal condition, the hemispherical shell made of carbon fiber material requires maximum hoop stress at the external surface as compared to the magnesium/polypropylene material. The transversely isotropic material hemispherical shell more convenient than that of isotropic material hemispherical shell. Results have been discussed numerically and graphically.
