摘要

研究了建立复杂层合结构有限元模型的方法.考虑到复合材料叶片根部结构具有重复铺层的特点

用子层刚度方法计算了其等效材料性能;采用ANSYS有限元软件按单一材料建立了根部的有限元模型

并讨论了载荷对边界条件和螺母-孔接触状态的影响.计算的[0°/±45°]三向层合板等效模量E1与实验值吻合良好;分别按等效模型和层合单元模型进行数值模拟所得到的位移误差很小

表明该方法具有较高的精度.所建立的模型可用于根部结构的受力分析.

Abstract

Method for FE modeling of complicate layered structures was investigated.In consideration of the characteristic of repeated layers in root structure of wind turbine blade

the sub-laminate method was introduced for calculating equivalent stiffnesses

the FE model of root structure was established while it was treated as unique material

the effect of loads on boundary conditions and contact states between screw nuts and holes was also discussed.The calculated equivalent modulus E1 of [0°/±45°] tri-axial laminate was in good accordance with tested result.Numerical simulation shows little difference between displacements obtained by equivalent model and layered element model respectively

which indicates good accuracy of the method.The established FE model can be used for further stress analysis of root structure.
