摘要:拉索预紧力直接影响拉索式垂直轴风力机的变形,预紧力要能适应不同风速和不同运行状态下的作用力,使叶片变形量满足结构规范要求。通过分析拉索式垂直轴风力机的计算参数和受力情况,建立风力机静止状态和运行状态的两种计算模型,利用SolidWorks Simulation软件对拉索式垂直轴风力机模型进行力学计算分析。计算结果表明,通过施加合适的预紧力,垂直轴风力机叶片的变形能够控制在较小的范围,满足风力机叶片的刚性要求,拉索式垂直轴风力机结构是可行的,计算模型简单有效。

Abstract:The blade deformation of cable-pulling type vertical axis wind turbine is mainly caused by cable preload. The magnitude of cable preload needs to be adaptable to the changes of wind force under different wind speeds and operating conditions, so as to meet the rigid requirements of wind turbine blade. By analyzing the calculation parameters and force conditions of cable-pulling type vertical axis wind turbine, two calculation models in static state and in operating state are established. Mechanical calculation and analysis is conducted by using the SolidWorks Simulation software. The results show that the blade deformation can be controlled in a small range by applying proper cable preload, which meets the rigidity requirement of wind turbine blade. The structure of the cable-pulling type vertical axis wind turbine is feasible, and the calculation model is simple and effective.
Key words:vertical axis;wind turbine;cable-pulling type;cable preload
