摘要:
针对现有大型垂直轴风力发电机组塔架存在的不足，提出了一种新型兆瓦级H型垂直轴风力发电双三角形式的塔架，计算了塔架所承受的永久载荷和风载。利用Ansys workbench有限元分析软件，对塔架进行了静强度和刚度分析。结果表明，在现有设计参数下，塔架的最大等效应力为7.1 Mpa，塔架的最大变形位于最高处，为0.04 m，强度和刚度均满足要求。
Aiming at the deficiency of existing large vertical axis wind turbine tower, a MW H-type vertical shaft wind power tower with double triangle is designed. The permanent load and wind load of tower structure are calculated. By means of Ansys workbench software, the static strength and rigidity of the tower are also analyzed. Numerical simulation results show that the maximum deformation and the maximum stress of the tower are within the allowable range in the condition of given design parameters.
