摘要
研究了不同种类和厚度的芯材对风力发电叶片力学性能的影响,重点开展了芯材对叶片稳定性和应力的分析。结果表明:同种芯材随芯材厚度增加,叶片的应力降低,稳定性增加;不同芯材材料的剪切模量越大,叶片的稳定性越高。研究结果为风电叶片结构设计优化提供了理论指导。
The influence of core material with different categories and thicknesses on wind turbine mechanical propertiesblade was studied with an emphasis on the analysis of the impact of core material on blade stability and stress. The resultsshowed that for the same core material,the blade stress decreases and the stability grows when thickness increases;fordifferent core materials,the blade stability increases with larger shear modulus. The results of this study may provide theoreticalguidance for the optimal design of blade structures.
