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.
