摘要
在风力发电产业的持续革新的背景下,风力发电机组不断向着大型化方向发展,传统的规范经验算法难以满足新形势下的风机基础计算的精度要求,因此需要借助有限元数值模拟等分析计算方法对工程设计提供更精确的指导。本文提出了一种锚栓式风机基础有限元模型的建立方法。模型将不同组件分别建模再根据空间位置组合为整体,并利用过渡网格的方法对模型进行网格划分,在提高了模型真实有效性的前提下保证了计算效率。
With the development of wind power industry,the capacity of wind turbine increases greatly.Under this background,the traditional designing method based on Codes Standards or empirical formulas can not precisely reflect the stress-strain characteristics of the wind turbine foundations.A simulation method of anchor-bolt wind turbine foundation is put forward.According to this method,the foundation is separated into several components which constructed independently.All components will be assembled based on the relative positions.Besides,a transition grid is introduced in meshing process to improve the efficiency of calculating.
