摘要
风力发电机塔筒的模态分析对于避免风机整体共振、提高其安全稳定性具有重要的意义。运用Pro/Engineer软件对塔筒进行三维建模,通过ANSYS Workbench软件对风力发电机塔筒结构进行模态分析和额定风速下的预应力模态分析,从而求解出风力发电机塔筒结构的模态参数,并得到塔筒的固有频率和振型特征,进而评价该风机塔筒的振动特性。
The modal analysis of wind turbine tower is essential to avoid the whole resonance,and has an important significance in improving security and stability of the wind turbine.The three-dimensional model of a wind turbine tower is built by use of Pro/ Engineer software.The modal analysis and preload stress modal analysis under the rated wind speed are conducted on the wind turbine tower by the software of ANSYS Workbench so as to identify the modal parameters of the tower,the natural frequency and vibration features,and then to evaluate the vibration characteristic of the wind turbine tower.
