Automatic finite element modeling of wind turbines blade based on MATLAB

The blade which can extract energy from wind plays a key role in a wind turbine system. Recently, finite element technology has been widely used in modern wind turbine blade design and analysis. However, due to the extremely complicated geometry shape and structure lay-out of the blade, finite element modeling of the blade becomes a quite challenge task and consumes a lot of time. In order to improve the efficiency of wind turbine blade design and analysis, this paper integrates Matlab language and APDL (Ansys Parametric Design Language) to develop a Matlab GUI (Graphic User Interface),which can generate the APDL commands used for building up the finite element model of blade while complete the blade geometry design. A 10kW fixed-pitch stall-regulated wind turbine blade is chosen as a case study to demonstrate the efficiency, accuracy and practicality of this method
