Structural Analysis of Wind Turbine Epicyclical Gear System by FEM

Abstract

Damages in gears may be a result of overload, inadequate operating conditions, or simple fatigue during power transmission. This paper studies the structural analysis by the finite element method of the gearbox of the wind turbine with an epicyclical gear system, under different excitation conditions. This analysis was according to the variation of operating mode or the type of epicyclical gear train. It gives us a vision of the concentrations of stress, in order to minimize the propagation of cracks and to estimate the lifecycle of the system. This investigation will play a very important role in the correct functioning of the power transmission system. In addition, it gives us an idea about the wind turbine gearbox vibration, so the compound that causes more noise. The design procedure has been detailed in the rest of the paper under the CAO software and the result of the numerical simulation has been evaluated by using Ansys software.
