Abstract

Abstract: Wind turbines are critical in structural behaviour, which are characteristically using the wind in order to produce power. In wind machines, blades are considered to be an important component because of its critical profile at different sections, weight, and the structural parameters with relatively high amplitude and high frequency. Life-cycle estimation of wind turbines is crucial to develop their design and maintenance process, since they should have more lifespan with minimum foreign object disruptions as well as low probabilities of failures. Wind turbine is eco friendly technology; it should provide a high lifespan of its whole set up by reduces the major failure factors. Due to the effect of aerodynamic loads acts in the wind turbine blades may cause to fail at unpredictably high an amount, which creates the wind turbine to make fatigue analysis as important factors in its performance. Fatigue life and its analysis of each rotating component is one of the major factors of concern due to the terrible failures that can result from it. In this paper, the fatigue behaviour of wind turbine blade in response to different frequencies has established to the level that the prediction of working lifespan is fitting an essential part of the design process also compare the suitability of a wind turbine blade with different composite materials such as Kevlar, Glass Fiber Reinforced Plastic (GFRP) and Carbon Fiber Reinforced Plastic (CFRP) by simulates the displacement and principal stress using numerical method. The reference component of this paper is modeled by using CATIA. A numerical model of the blade was created using ANSYS Workbench 16.2 in order to estimate the typical mode shapes occurring within the blade based on a wind profile and mass approximating the location where these blades are expected to vibrate. Also, fatigue life of wind turbine blade analyzed for three composite materials and the results are compared in order to find out the optimum material body.
