摘要
暂态响应分析是研究风电机组塔架动力学特性的有效方法之一。以某风电场2.0 MW风电机组为例,采用有限元瞬态计算方法模拟了塔架在脉动风载荷作用下的振动特性。研究结果表明,在某一平均风速下脉动风对塔架振动有较大影响,塔架在脉动风的作用下以一阶振型为主,高阶振型分量可忽略不计。
Transient response analysis is one of the effective methods to study the dynamic characteristics of wind turbine tower.The vibration characteristics of the tower of a 2.0MW wind turbine under fluctuating wind loads are simulated with the finite element method.The results show that the fluctuating wind has great influence on the vibration of the tower,and the tower is dominated by first-order modes.However,the components of higher-order modes can be neglected.
