Viscous damper-based power transmission tower wind-induced vibration control method and equipment
The invention belongs to the technical field of power transmission tower wind resistance. The invention provides a viscous damper-based power transmission tower wind-induced vibration control method and equipment. The method comprises the following steps of: obtaining a wind load parameter and a residual structural performance parameter of a power transmission tower; performing wind resistance evaluation on the power transmission tower according to the wind load parameter and the residual structure performance parameter; determining a weak deformation position of the power transmission tower according to a wind resistance evaluation result; and arranging a viscous damper at the weak deformation position of the power transmission tower according to a preset damper arrangement mode. The viscous damper is arranged at the weak position of the power transmission tower, so that the vibration resistance of the weak part of the power transmission tower structure is improved, deformation and internal force of wind-induced vibration are reduced, the wind resistance of a tower line system is improved, and the failure probability of the tower line system under strong wind is greatly reduced.
本申请属于输电塔抗风技术领域。本申请提供了一种基于粘滞阻尼器的输电塔风致振动控制方法及设备，其中本方法包括如下步骤：获取风荷载参数和输电塔的剩余结构性能参数；根据风荷载参数和剩余结构性能参数对输电塔进行抗风性能评估；根据抗风性能评估的结果确定输电塔的变形薄弱位置；在输电塔的变形薄弱位置按照预设阻尼器布置方式布置粘滞阻尼器。本申请在输电塔的薄弱位置布置粘滞阻尼器，使得输电塔结构薄弱部分的抗振动能力得到提升，降低了风致振动的变形和内力，提高了塔线体系的抗风能力，塔线体系在强风下的失效概率大大降低。
