摘要(Abstract)：
针对输电塔的结构特点,结合自然风特性,提出采用自回归模型方法求取铁塔脉动风随机过程。应用脉动风速和脉动风压的概率统计方法,找出适合输电塔的自回归模型的阶数。在通用有限元程序ANSYS中实现了输电铁塔水平脉动风压时程模拟,经算例分析,计算快速准确。
According to the features of structural style of transmission tower,considering the correlation of the natural wind,the method of auto-regressive model(AR model)in time series analysis is presented.The suitable step number of auto regression models of certain transmission tower is found.A real project is treatˉed as an example in ANSYS.The results indicate that analysis and treatment methods presented here are reasonable and feasible.
