摘要 本文介绍了一种新型的斜轴式风力机。阐述运用画法几何正投影原理分析其风能接收情况,优化轴线的合理倾角以及在风载荷作用下,叶片和风轮的振动规律。通过图形推导,得到斜轴风轮的气动力学空间数学模型。并与我们研制的斜轴式风力发电机进行对比,得到满意的结果。从而为该种机型的优化设计提供有益的参考。 A new type inclined axis wind turbine is introduced in this paper. By means of the principle orthographic projection of discrip.tive geometry, the receiring of wind energy is analysed; the inclined angle of axis is optimized and the law of the windage vibration of blade and turbine is drawn. By the analysis of figures, the air dynamical mathimatical model of turbine is set up. In contrast with our inclined axis wind turbine, the result is satisfactory.This paper will be benefit to the optimization design of this kind of wind turbine.
