Power transmission iron tower wind-resistant damping structure based on negative Poisson effect
The invention discloses a power transmission iron tower wind-resistant damping structure based on a negative Poisson effect. The power transmission iron tower wind-resistant damping structure comprises a first spherical hinge mounted on a damping structure support; the first spherical hinge is connected with the bottom of a damping structure used for damping energy dissipation through a spherical hinge rod, and the top of the damping structure is sequentially connected with the spherical hinge and a second chain rod through a first chain rod; the damping structure support is mounted on a tower footing, and an iron tower is mounted on the tower footing; the damping structure comprises a negative Poisson ratio component; the top end of the negative Poisson ratio component is connected with the bottom end of the first chain rod; and the bottom end of the negative Poisson ratio component is connected with a reset spring, and the bottom end of the reset spring is fixed to the bottom of the inner side of the damping structure. The damping structure designed by the invention is mounted on the power transmission tower, the weight of a tower body is not affected, meanwhile, additional unknown vibration of the tower body is avoided, the structural form is simple, the manufacturing cost is low, and maintenance, production, transportation and mounting are easy.
本发明公开了一种基于负泊松效应的输电铁塔抗风阻尼结构，包括安装于阻尼结构支座上的第一球形铰链；第一球形铰链通过球形铰链杆与用于阻尼消能的阻尼结构的底部相连接，阻尼结构的顶部通过第一链杆依次与球形铰链和第二链杆相连接；阻尼结构支座安装于塔基上，塔基上安装有铁塔；阻尼结构包括负泊松比构件；负泊松比构件的顶端与第一链杆的底端相连接；负泊松比构件的底端与复位弹簧相连接，复位弹簧的底端固定于所述阻尼结构内侧的底部。本发明设计的阻尼结构安装于输电塔上，不影响塔身的自身的重量，同时避免引起塔身的附加未知振动，结构形式简单，且造价低，易于维护，生产、运输和安装。
