[提要]针对调频弹簧质量阻尼器( TSD)对单管圆锥钢塔风振控制的机理作了深入研究。使用通用有限元分析软件ANSYS,结合具体工程对TSD的风振控制进行了动静力分析,分析了控制参数对控制效果的影响。研究表明,TSD可以有效地抑制单管圆锥钢塔的风振反应。[关键词] 调频弹簧质量阻尼器(TSD) 单管圆锥钢塔 风振控制Abstract: The mechanism of wind vibration control of single tube cone steel towers using tuned spring mass damper( called TSD)has been studied. Phased on real projects, FFA software ANSYS is applied to make the static and dynamic structural analysis of wind violation control of TSD, and the related parameters are investigated. The studies confirm the effectiveness of TSD in abating the wind-induced vibration responses.Keywords: tuned spring mass damper( TSD); single tube cone steel tower; wind vibration control
