摘要
为了获取风电叶片玻璃纤维布铺层装备承载横梁的结构力学性能,文章对承载结构进行试验,得到其弯曲夹角为0.034 6°,高度收缩量为3.03 mm。通过建立承载横梁的有限元模型,得到了横梁受力变形关系,并进一步构建了补偿方程。模拟及现场试验结果表明,基于有限元法的装备力学分析能较真实反映承载横梁的工作特性,补偿方程能有效弥补横梁变形,变形误差小于0.16 mm。
In order to obtain the mechanical properties of the load beam for wind turbine blade fiberglass fabric laying equipment,the load beam is tested and knows that the angle of the equipment is 0.034 6°.In addition,height reduced by 3.03 mm.The finite element model of the beam is established,and the relationship between the force and the deformation of the beam is obtained.Then,the compensation equation is established.The results show that mechanical analysis based on the finite element method can react the working characteristics of the beam truly.At the same time,the compensation equation is effective and can compensate the deformation of the beam with an error of less than 0.16 mm.
