| 摘 要： | 计算大型风力发电机组的整体稳定性和动态特性的关键是要计算出机组顶端的水平位移，由于大型风力发电机组结构通常比较复杂，塔架均采用变截面形式，各截面的刚度并非常数，因此使计算过程变得复杂、繁琐，以变截面塔架结构为例，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，从而可简便地求出其顶端的水平位移。

| Abstract: | The horizontal displacement calculation of the top of large-scale wind turbine tower is a key point in calculating the stability and dynamic characteristics of wind turbine.Because large-scale wind turbine structure is usually complicated,tower construction is variable cross-section,and the rigidity of each cross-section is variable,the calculation becomes rather complex and troublesome.Taking variable cross-section tower construction as an example,based on the same rigidity,the corresponding equivalent ine... |
