Wind turbines (the windmill) is a conversion device that turn wind energy into mechanical energy, electrical energy or thermal energy. The vertical axis wind turbine has some advantages over the horizontal axis wind turbine. The small H-vertical axis wind turbine blades are analyzed. The load in different working environments are also analyzed. Stress calculation and checking methods are discussed. It can provide a reference for small H-vertical axis wind turbine blade design.%风力发电机(简称风车),是一种将风能转化为机械能,电能或热能的转换装置.比较了垂直轴风力发电机与水平轴风力发电机的优势后,对小型H型垂直轴风车叶片的进行了分析,给出了在不同工作环境中的载荷分析,并对叶片的应力计算及校核方法作了讨论,为小型H型垂直轴风车的叶片设计提供了参考.
