摘要针对强风和断线冲击作用下高压输电塔易发生的较大幅度振动问题，本文开发了一种弹簧板式电涡流全向调质阻尼器（ECTMD）以减轻此类结构的风致振动和断线冲击效应。本文采用的ECTMD相比以往类似装置，其突出优点为使用非接触式的电涡流阻尼，构造简单且无内摩阻，微振动下即可启动，且非对称悬臂梁摆式构造使其具有全向抑振功能。运用数值模拟和气弹模型风洞试验对有无ECTMD时的某50m高输电塔振动响应进行了分析验证，计算和试验结果表明：本文开发的ECTMD沿各方向均有一定的减振效果，在质量比2%左右时，加速度减振率为18%~27%，位移减振率为10%~25%。因风作用下塔身1阶共振相比背景响应占比很小，故加装TMD装置对结构风振的抑制相对有限，但其能将结构阻尼值提高3倍左右，对于减小断线等冲击荷载效应会有较好效果。

Abstract：Aiming at high voltage transmission towers’ obvious vibration problems under strong wind and power line’s breakage impact, a spring plate type eddy-current tuned mass damper (ECTMD) was developed and applied to reduce their wind-induced vibration and power line’s breakage impact load effect on them. Compared to previous similar devices, it was shown that ECTMD’s outstanding advantage is using contactless eddy current damping, its structure is simple without internal frictional damping, and it can be started under micro-vibration; in addition, its asymmetric cantilever beam pendulum type structure makes itself has omnidirectional vibration suppression function. Adopting numerical simulation and aero-elastic model’s wind tunnel tests, vibration responses of a 50 m high transmission tower with and without ECTMD were analyzed and verified. Calculation and test results showed that this type ECTMD has a certain vibration reduction effect in all directions; with the mass ratio of about 2%, its vibration acceleration reduction ratio is 18%-27%, and its vibration displacement reduction rate is 10%-25%; due to the ratio of the tower’s first order resonance amplitude to background response one is very small, the suppressing effect of ECTMD on the tower’s wind induced vibration is relatively limited, while it can increase the structural damping by about 3 times, so it has a better effect to reduce power line’s breakage impact load effects on high voltage transmission towers.

Key words： power transmission tower；vibration control；eddy-current tunned mass damper；numerical simulation；wind tunnel test
