Research of Turbine Tower Optimization Based on Criterion Method

Tower cost makes up an important part in the whole wind turbine construction especially for offshore farms. The main method to reduce tower is weight by optimum design. This paper proposes a two-level optimization criterion optimal design of steel conical considering different structural reliability and uncertainty, along with discreteness variables such as thickness bolt type. In first level, shell geometry can be obtained section method; second bolted connections flanges are designed based on results level. Then, summarized analysis iterative calculation performed obtain constant strength rigidness. will play role customized
