Abstract

To simplify the wind turbine model, we used SolidWorks and ANSYS software. Boundary conditions were selected to ensure safe and stable operation of the wind turbines. The deflection analysis of the rotor system showed that the maximum deflection of the shaft was 2.4% of the air gap, which met the design requirements. The modal analysis of the wind turbine demonstrated that resonance would not occur, because the natural frequency was not equal to the exciting frequency of the impeller. Our results could provide a reference for large-scale design and strength check of wind turbines.

基于模态理论的5MW半直驱永磁风电机轴系统强度及模态分析

摘要

为了简化风力涡轮机模型，我们使用了 SolidWorks 和 ANSYS 软件。选择边界条件以确保风机安全稳定运行。转子系统挠度分析表明，轴的最大挠度为气隙的2.4%，满足设计要求。风力机的模态分析表明不会发生共振，因为固有频率不等于叶轮的激振频率。研究结果可为风力发电机组的大规模设计和强度校核提供参考。
