Catastrophic Failure Analysis of a Wind Turbine Gearbox by the Finite Element Method and Fracture Analysis

open access: yesDesigns
The wind turbine gearbox, used as a multiplier, is one of the main components directly related to a wind turbine’s efficiency and lifespan. Therefore, strict control of the gearbox and its manufacturing processes and even minor improvements in this ...

Software Development of High-Precision Ephemerides of Solar System [PDF]

open access: yesJournal of Astronomy and Space Sciences, 1995
We solved n-body problem about 9 plants, moon, and 4 minor planets with relativistic effect related to the basic equation of motion of the solar system. Perturbations including figure potential of the earth and the moon and solid earth tidal effect were ...

Avoiding resonance capture in multi-planet extrasolar systems [PDF]

open access: yesarXiv, 2017
A commonly noted feature of the population of multi-planet extrasolar systems is the rarity of planet pairs in low-order mean-motion resonances. We revisit the physics of resonance capture via convergent disk-driven migration. We point out that for planet spacings typical of stable configurations for Kepler systems, the planets can routinely maintain a
