摘要: 基于Python开发了风电叶片预埋叶根连接有限元建模脚本,通过预埋叶根连接几何模型参数化,同时自动进行材料属性设置、接触设置、网格划分及载荷约束设置,实现了预埋叶根连接参数化有限元建模。通过有限元分析软件对叶片双头螺栓和轴承端螺栓施加预紧力,在预紧力和外载共同作用下,利用有限元分析软件进行接触非线性计算,依据VDI 2230和GL 2010分析了预埋叶根连接螺栓及螺栓套与界面之间的静强度和疲劳强度,为预埋叶根连接设计优化提供指导和参考。基于Python开发的风电叶片预埋叶根连接参数化有限元建模脚本,缩短了风电叶片预埋叶根连接详细设计及结构校核周期。

Abstract: A finite element modeling script for wind turbine blade embedded root connection was developed based on Python, through the parameterized geometric model of the wind turbine blade embedded root connection, the material properties, contact settings, grid mesh and loads constraint were set automatically, and realized the parameterized finite element modeling of the wind turbine blade embedded root connection. The pretension is applied to the blade bolt and hub bolt by finite element analysis software. Under the pretension and the external loads, contact nonlinear calculation is performed according to the finite element calculation results. The static and fatigue strength of the embedded root connection bolt and insert connection in laminate is analyzed through GL 2010 and VDI 2230 standard, providing guidance for the wind turbine blade embedded root connection design optimization. Embedded root connection finite element modeling script developed on Python significantly shortened the detail design and structural strength verification cycle of the wind turbine blade embedded root connection.
