摘要
垂直轴风力机有着优良的气动性能,近年来受到人们越来越多的关注。介绍了风力机结构动力特性在国内外研究现状。对风力机的结构振动特性进行了研究,分析了工作状态下风机的动力刚化问题。对某垂直轴风力机进行不同转速下的固有频率分析,绘制Campbell图,并计算了风机的临界转速,以判断其工作状态是否安全。
Because of its advantageous aerodynamic performance, the vertical-axis wind turbine has gained more and more attention. Research on the dynamic characteristics of the wind turbine＇ s structure both at home and abroad was presented, and the turbine＇ s structure vibration characteristics were analyzed, as well as its dynamic stiffening problem. Analysis of a vertical-axis wind turbine＇ s natural frequency with different rotating speeds was also carried out, the Campbell diagram was drawn, and the wind turbine＇s critical rotating speed was calculated to iudge the turbine＇s safety.
