摘要
对水平轴小型风力发电机的工况进行了分析,利用贝兹理论计算了主轴载荷,给出一种用于水平轴小型风力发电机中主轴永磁力轴承的支承方案,完成了永磁力轴承数学模型的建立与结构的设计,并利用ANSYS软件计算得出永磁力轴承径向力与轴向偏心位移之间的关系曲线。
The working condition of horizontal axis small- scale wind turbine is analyzed, the load of spindle is calculated through Betz＇ Law, and then a kind of support project is given, which suits for horizontal axis small - scale wind turbine. The designs of permanent magnetic bearings are performed, and their mathematical models are established. Finally, the distribution of magnetic field lines and radial force vector are analyzed , getting the curves between radial force and the axial offset displacement of radial permanent magnet bearings by the finite element software ANSYS.
