摘要：提出一种索塔式新型风力发电塔架，确定了纤绳锚固点高度、初张力及纤绳与地面夹角等参数；以实际工程为背景，根据ANSYS一阶优化方法，编制了索塔式风电塔架和单管塔的APDL优化程序，对两种塔架分别进行截面优化和形状优化。对比结果表明，索塔式塔架具有比单管塔基础工程量小﹑运输方便、施工难度小等优点。就索塔式塔架而言，增大纤绳初张力可有效减小塔底弯矩，并在一定范围内增大纤绳初张力可有效提高塔架稳定性。

Abstract：A new type of wind turbine tower of cable-towerstructure was proposed.The height of the cable anchorage point, the initial tension, and the angle between cable and ground were determined. With the first order optimization method in ANSYS,the calculation algorithm of cable-towerstructure and single-pipe tower was developed based on the practical project. Using the optimizationalgorithm, the optimization of the sectionsize and shape of two tower structures was carried out. It was found that compared with the single-pipe tower, the cable-towerstructure has quite a lot of advantages , such as the relatively higher first natural frequency and stiffness, the relatively lower foundationquantities, convenient transportationand less construction difficulty and etc.. For the cable-towerstructure,increasing the cable initial tension can effectively reduce the bottom bending moment of the tower, while increasing the cable initial tension can effectively improve the stability of the tower to some extent.
