摘要
为了进一步减轻低风速风电叶片的重量及载荷,以长度为54 m的某2 MW风电叶片为研究对象,构建了玻碳混杂叶片铺层结构设计模型,基于Matlab和ANSYS参数化建模和分析方法,对优化设计的玻碳混杂铺层结构叶片进行了强度、载荷特性、质量与最大变形量分析。研究表明:优化后的叶片质量降低了32.46%,其动态载荷及叶尖变形量有明显的减小;在保证叶片优化前后具有相同刚度的前提下,优化叶片的最大拉伸应力明显降低。本文的研究对低风速风电叶片的轻量化设计具有重要的参考意义,有助于降低风电叶片的成本。
In order to further reduce the weight and load of low wind speed wind turbine blades,a design model of glassy carbon hybrid blade lamination structure was established based on a 2 MW wind turbine blade with a length of 54 meters.Based on the parametric modeling and analysis methods of MATLAB and ANSYS,the strength and load of the optimized glassy carbon hybrid laminated blade were carried out,as well as the characteristic,mass and maximum deformation analysis.The results show that the optimized blade mass decreases by 5.34%,and its dynamic load and tip deformation decrease significantly.On the promise of ensuring the same stiffness before and after optimization,the maximum tensile stress of the optimized blade decreases by 28.66%.This study provides important reference for lightweight design of low wind speed wind turbine blades,which is helpful to reduce the cost of wind turbine blades.
