摘　　要：在全面分析垂直轴风力发电机主轴结构和受力的基础上,运用ANSYS Workbench建立垂直轴风力发电机主轴的参数化有限元模型。以主轴的强度和刚度为约束条件,以主轴质量最小为目标。对主轴的内径、支承跨距、轮辐与支承的距离和轮辐跨距进行了优化计算。并对优化前后结果进行了对比分析。计算结果表明:垂直轴风机主轴结构优化后,在保证各项力学性能的前提下,主轴质量得到较大幅度的减小。从而降低了主轴的生产成本,提高了垂直轴风力发电机的市场竞争力。With the comprehensive analysis of structure and stress, the vertical axis wind turbine spindle parameterized element model is established by using ANSYS Workbench. The inner diameter of the shaft, bearing span,spokes and supporting distance and spokes span are optimized in the way of the main shaft of strength and stiffness as constraint conditions and the minimum spindle weight as the goal. The results were compared before and after the optimization analysis. The calculation results show that the .weight of spindle is greatly reduced on the premise of guarantee the mechanical properties after structure optimization. The vertical axis wind turbines improve the market competitiveness by reducing the spindle production cost.
