500kV换流站钢构架自然风载振动仿真分析
摘要
针对某±500 kV换流站直流滤波器悬吊钢架
开展自然强风载抖振(随机振动)研究。首先进行脉动风速模拟
通过将脉动风荷载施加到有限元模型上
同时引入瑞丽阻尼进行自然风载作用下的抖振研究
得到构架横梁风致随机振动时程曲线
振动最大幅值为3.39×10-4m。
Abstract
Aimed at DC filter suspension architecture for a ± 500 kV converter station
the research about natural strong wind buffeting( random vibration) is carried out. Firstly
the fluctuating wind speed analog by fluctuating wind load is applied for the finite element model
and then the Ruili damping is introduced to research buffeting under natural wind loads
and frame beam wind speed time history curves are obtained. The maximum vibration amplitude is 3. 39 × 10- 4m.
