大型风力发电机组塔架刚度的研究

Research on large scale wind driven generator group tower rigidity

以大型风力发电机组最常用的变截面(锥形)塔架结构为例,根据刚度相等的条件,推导出变截面塔架结构在横向力、弯矩及均布载荷作用下对应的当量惯性矩的计算公式。从而可简便地利用材料力学中的经典公式求出其顶端的位移,达到塔架刚度计算的目的。

Taking the most common variable cross-section tower construction as an example, based on the same rigidity, this article deduces the corresponding equivalent inertia moment formula of variable cross-section construction under the effects of horizontal force, flexural torque and rectangular distribution burdening. Thereby it can find out the top displacement by simply makes use of classical formula in material mechanics, reaches the purpose of calculating tower rigidity.
