基于ANSYS对大型垂直轴风力机塔架进行静力学分析、动力学分析及结构优化。首先，根据风力机的功率确定塔架的大体尺寸；然后，对塔架进行静力分析，并对塔架承受最大载荷时的最大应变进行强度校核；对塔架的动力学分析包括有预应力的模态分析和地震谱响应分析。ANSYS优化主要是通过改变塔架的厚度提高其固有频率，避免因塔架在发电机的激励下共振而产生的破坏。对塔架的力学分析能够在满足力学性能的前提下使塔架的质量最轻，降低塔架的制造成本。

The statics analysis,dynamics analysis and structural optimization of tower frame of large vertical axial fan were presented based on ANSYS. First of all,the size of tower frame was determined according to the power of fan. Then,statics analysis for the tower frame was carried out. And, the strength check for the maximum strain of the tower frame under the maximum load was discussed. Dynamics analysis including prestressed modal analysis, seismic response spectrum analysis was performed. The optimization based on ANSYS was obtained by changing the thick- ness of the tower frame to increase the inherent frequency so as to avoid the damage of tower frame induced by the resonance of generator excitation. The mechanical analysis of the tower frame can ensure the lightest weight of the tower frame under the premise of mechanical properties and reducing the manufacturing cost of tower frame.
