载荷对无动力风机的影响

Effect of Loading Magnitude on Unpowered Turbine Performance

无动力风机广泛用于大型建筑的通风换气。作者之前提出了一种基于无动力风机的小型发电装置。本文结合实际中无动力风机的具体尺寸,利用SolidWorks三维建模软件对无动力风机进行了三维建模,并通过对其三维模型进行有限元分析,模拟其在各个自然环境条件下的应力变化,最终得出了无动力风机在自然条件下的应力应变关系,为之后的研究提供了良好的基础。

It is generally accepted that the unpowered fan is widely used in ventilation for large buildings.The authors have previously proposed a small power generator based on unpowered fans.,This paper uses SolidWorks 3d modeling software to model the unpowered fan in three–dimensions.Through the finite element analysis of its three-dimensional model,the stress changes under different natural environment conditions are simulated.Finally,the stress and strain relationship of unpowered fan under natural conditions is obtained,which provides a good foundation for the later research.
