摘要
以浙江运达风力发电工程有限公司自行设计、生产并已投入商业化运行的1.5 MW大型风力发电机组为例,根据风力机运行时主轴的受力状况,从力学的角度论证了主轴支承获得最佳抗弯刚度的跨距,并介绍了一种用迭代法求解主轴支承最佳抗弯刚度跨距的近似计算法及增加主轴刚度的有关措施,以供风力机设计人员参考。
Taking the example of the 1. 5MW wind turbines which was developed and produced by Windey, and has been in good commercial operation till now, the span of main shaft supporting the optimization bending rigidity was demonstrated in accordance with the main shaft＇ s stress when the wind turbine was operating, and an approximate calculation, i.e. iterative method, was introduced to get the best span of main shaft support for best bending rigidity in views of mechanics, as well as some measures to increase the main shaft rigidity, providing reference for wind turbine designers.
