中文摘要：
以风阻尼器为基本模型,设计了适合塔器应用的钟摆式阻尼器,确定钟摆阻尼器尺寸与其频率的关系式,以此为基础设计钟摆式阻尼器。采用适当的几何相似系数,建立实验室小试模型,通过自由振动法测量系统的阻尼比,验证阻尼器效果。以此作为参考标准,对比分析了各阻尼器安装在不同位置处的效果,研究了质量比与安装位置对阻尼器效果的影响。通过瞬态动力学分析与实验结果进行对比验证,并分析阻尼器数量对阻尼器防振效果的影响。研究工作为塔器防振中阻尼器的设计与应用提供了参考依据。
英文摘要：
A ball damper suitable for column in chemical industry is designed based on wind damper and the relationship of damper measurement and frequency is also determined. In this paper, an experimental model was built by suitable geometrically similar coefficient for verifying the effects of damper. The damp ratio was determined through free vibration method, which could verify the damper effect. As the reference standard, a study was researched through the effect of different dampers in different installation positions of column model. The experimental results was contrast with the result of transient dynamics. The effect caused by quantity of damper was also studied. The research of this paper has provides a reference basis to design the damper in column vibration control.
