Wind energy being simply available, naturally, friendly, and cost-effective, has become one of the world's rising renewable energy sources of electricity generation. This work presents the solution of the steady-state problem using the Finite Element Method to compute stresses and deflections of the blade’s of wind turbine during the region of (rated speed) condition. A 10 KW 3-bladed horizontal axis wind turbine blade (length of 1.5 m with rotor diameter 3 m) was selected. It was created three-dimensional model of wind turbine blades using SOLIDWORKS 2019 software. In the next step, it was exported the new model to ANSYS/workbench 2019 to analyze the stresses. It was investigated the influence of two important factors which are the rotational speed of the blade, and the type of materials on the stresses and deflections. The results illustrated the stresses and deflections. It was found when using Aluminum Alloy the deformation was less than instead of using the rest materials mentioned in this work at constant thickness, in addition, when using Carbon Fiber 395 Gpa the values of stresses are less when other materials at low values of rotational speed for the model of blade.

摘要

Wind energy being simply available, naturally, friendly, and cost-effective, has become one of the world's rising renewable energy sources of electricity generation. This work presents the solution of the steady-state problem using the Finite Element Method to compute stresses and deflections of the blade’s of wind turbine during the region of (rated speed) condition. A 10 KW 3-bladed horizontal axis wind turbine blade (length of 1.5 m with rotor diameter 3 m) was selected. It was created three-dimensional model of wind turbine blades using SOLIDWORKS 2019 software. In the next step, it was exported the new model to ANSYS/workbench 2019 to analyze the stresses. It was investigated the influence of two important factors which are the rotational speed of the blade, and the type of materials on the stresses and deflections. The results illustrated the stresses and deflections. It was found when using Aluminum Alloy the deformation was less than instead of using the rest materials mentioned in this work at constant thickness, in addition, when using Carbon Fiber 395 Gpa the values of stresses are less when other materials at low values of rotational speed for the model of blade.
