摘　　要：小型家用垂直轴风力机是目前国内外研究的热点,探讨其结构动力学特性对于预防共振、稳定性控制和噪声控制具有重要的意义。本文使用有限元方法研究了某小型垂直轴风力机的结构动力学特性。首先采用Solidworks对风力机进行建模,然后利用ANSYS Workbench仿真软件对其进行求解,得到各部件的固有频率和振型。通过分析得到如下结论:在风力机各部件中,叶片柔性最大,易发生低频共振;塔架刚性最大,易发生高频共振。Small household vertical-axis wind turbine is a hot research topic at home and abroad.It is of great significance to explore its structural dynamic characteristics for preventing resonance,stability control,and noise control.In this paper,the structural dynamic characteristics of a small vertical axis wind turbine are studied by the finite element method.Firstly,the wind turbine is modeled by Solidworks and then solved by ANSYS Workbench simulation software to obtain the natural frequency and vibration mode of each component.The following conclusions are obtained through analysis.Among the components of the wind turbine,the blade is the most flexible and prone to low-frequency resonance,the tower has the largest rigidity and is prone to high-frequency resonance.
