小型风力发电机塔架分析及优化设计

Analysis and Optimization Design For a Small Wind Turbine Tower

塔架是风力发电机的重要受力组件,塔架的截面形状、塔架高度和最小直径对塔架的力学性能影响显著.提出基于遗传算法优化塔架的厚度和直径,避免因发电机的激励引起的共振、使塔架的质量最轻,降低塔架的制造成本.为风力发电机塔架的设计制造提供了理论依据.

The tower is an important force component of the wind turbine. The cross section shape, tower height and minimum diameter of the tower have significant influence on the mechanical properties of the tower. It is proposed to optimize the thickness and diameter of the tower based on genetic algorithm, avoid the resonance caused by the excitation of the generator, make the tower the lightest quality and reduce the tower manufacturing cost, which provides a theoretical basis for the design and manufacture of wind tur- bine tower.
