莱州湾3MW风力发电塔结构设计及实测研究

摘要

自振特性对风力发电塔的安全运行和动力分析具有重要意义.本文采用环境脉动实测方法,识别莱州湾3MW风力发电塔自振特性.结果发现,实测值与理论值较为吻合,说明梁板式预应力锚栓基础和反向平衡法兰的使用并不影响整体的刚度和频率.%The natural vibration characteristics has an important influence on the safety operation and dynamic anlysis of wind power tower. In this paper, the ambient vibration testing method is used to indentify the dynamic character of a 3MW wind power tower in Lai-Zhou bay. It is conclued that the testing result is very close to the theoretical value. The prestressed-anchor beam-slab foundation and the balance flange has no influence on the stiffness and the frenquency of the structure.
