为了研究输电塔线耦联体系的响应特性,并探究不同抗风分析模型之间的异同,利用有限元软件ABAQUS建立了多种抗风模型,并计算了各种抗风模型在不同风向角作用下的整体动力响应。结果表明在不同风向角作用下输电塔线之间的作用规律不同,且同种风向角下各种抗风模型互有特点。深入研究了塔线耦联体系的动力响应特性,并为风荷载作用下输电塔线耦联体系抗风分析的简化提供可能。
In order to study the response characteristics of transmission tower line coupling system and explore the similarities and differences between different wind resistance analysis models, a variety of wind-resistance models are established by using finite element software ABAQUS. The effects of various wind-resistance models on different wind direction angles Under the overall dynamic response. The results show that the action law of the transmission tower lines is different under the different wind direction angles, and the wind resistance models of the same wind direction have their own characteristics. In-depth study of the dynamic response characteristics of tower-line coupling system and provide the possibility of simplifying the wind-resistant analysis of transmission line coupled system under wind load.
