摘要:
采用Davenport 风谱模拟作用在大跨越输电线路钢管塔空间节点上的随机脉动风激励,并建立1 000 kV 大跨越钢管塔的Ansys 有限元模型,分析其动力特性和风振响应特征.基于钢管塔的动力分析结果,选取了调谐质量阻尼器减振、粘弹性阻尼器减振、粘弹性阻尼器与调谐质量阻尼器组合减振的三种控制方案,并评价了不同方案的减振效果.结果表明,单独采用质量阻尼器进行风振控制的效果略优于单独采用粘弹性阻尼器的方案,但优势并不显著,罕遇工况下易造成动力放大效应.调谐质量阻尼器与粘弹性阻尼器联合控制方案中,由于控制扭转的调谐质量.
Abstract:
A finite element model with ANSYS was created for an analysis of wind-induced response and vibration control of steel tubular tower in the 1000 kV large span crossing transmission line. Randomly fluctuating wind on spatial joints of the model was simulated using Davenport spectrum. Based on analysis of tubular tower dynamic characteristics and wind-induced response, three vibration control systems were used: tuned mass dampers (TMD), viscoelastic dampers (VED), TMD-VED were discussed to assess the vibration isolation effectiveness of vibration countermeasures in large-span crossing transmission tower. The result demonstrates that the damping performance of TMD is better than the VED, with limited significance, having adverse effects of dynamic magnification in accident causes. TMD with small mass in TMD-VED system offers limited effect for control torsional vibration. It is further shown that, VED is most viable method for reduction of wind-induced response, providing an approximately 9%~13% reduction of displacement responses and 20%~30% reduction of acceleration responses on tower body.
