摘要
叶片是风力机获取风能最为关键的部件之一。近年来,有限元技术已经广泛地运用到风力机叶片设计和分析中。然而,由于风力机叶片极为复杂的曲面外形和铺层结构,使得叶片有限元建模变成一项极具挑战性和耗时的任务。为了提高风力机叶片设计和分析的效率,本文结合Matlab语言和APDL(Ansys参数化设计语言)编程,开发了Matlab GUI(用户图形界面),能够在完成风力机叶片几何外形设计的同时,自动生成用于建立叶片有限元模型的APDL命令流。本文以一台10kW定桨距失速型风力机叶片的设计和有限元建模为实例,阐述其思想并验证了此方法的高效性、正确性和实用性。
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 modem 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 a- nalysis, 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.
