塔设备风致摆动及质量块减振效果研究

Study on Wind-induced Swing of Tower Equipment and Damping Effect of Mass Block

通过对塔设备风致摆动的分析,求解当外界力频率同塔设备的自然频率相等或者相近时塔设备的振动情况。计算了大高径比塔设备的自然频率与振动型式,以质量块滑动装置作为主要分析对象,研究质量环质量对减震效果的影响以及质量块滑动装置的安装位置对其减震性能的影响。提出一种可行的设计方法,设计了新型的质量块滑动装置,为工程实践提供参考。

Based on the analysis of the wind-induced swing of the tower equipment, the vibration of tower equipment was solved when the frequency of external force was equal to or close to the natural frequency of tower equipment.The natural frequency and vibration pattern of the tower equipment with large height to diameter ratio were calculated in this paper, taking mass block sliding device as the main analysis object, the influence of mass ring mass on damping effect and the influence of mass block sliding device installation position on damping performance were studied. And a feasible design method was proposed, which could provide some reference for engineering practice.
