摘要
相比于一般风力机塔架,格构式塔架具有容易制造,成本低,运输简单,安装方便和对生态环境影响较小的优势.根据质量分配设计了两种新型格构式塔架,完成了塔架的建模以及静应力分析和预应力模态分析.结果显示,所设计的格构式塔架能满足塔架的设计要求,其中三角分段格构式塔架的稳定性更好.
Lattice tower has the advantages of easy manufacture,low cost, simple transportation, easy in- stallation and smaller influence on the ecological environment. This paper has designs two kinds of new- type of lattice tower for wind turbines, and completes the tower model, static stress analysis and pres- tressed modal analysis. Results show that the lattice tower can meet the requirements of the design of the tower,and the stability of the triangular section lattice tower is better than the former one.
