摘　　要：为了提高风机吊装效率和安全性,提出一种具有多点附着的塔式起重机。与建筑用附着塔式起重机不同,风机塔筒和附着架的柔性与塔式起重机结构变形有耦合作用。文中采用力法及叠加法分析这种柔性环境下塔式起重机的附着特性,并与有限元的分析结果相比较,得到最优的理论计算方法,为这种塔式起重机的设计提供参考。In order to improve efficiency and safety of the wind driven generator hoisting, a tower crane with many at- tachments is designed. Unlike building tower crane, the flexibility of both the tower of wind-driven generator and attach- ment structure have an effect on the structural deformation of a tower crane. This paper utilizes the force method and the superposition method to analyze the attached feature of tower crane under the flexible condition. In comparison with the re- sults of FEM, an optimum method of theoretical calculation for the design of this kind of tower crane is proposed.
