摘要
岸边起重机结构中有许多长的弹性圆截面杆件,自振频率比较低,很容易发生横风共振。分析引起这类杆件振动的原因,介绍一些抑制风致振动的结构振动控制方法及相应的控振措施。提出利用抗扰条肋抑制此类风致振动的方法,并通过试验方法模拟了圆截面杆件的风致振动,取得一定的振动抑制效果。
There are many long and elastic round cross-section rod structures in quayside container crane, whose frequency are so low that it is easy to arouse crosswind resonance.This paper analyze the cause of vibration, and introduce some methods and measures of structural vibration control. The method using interference rib is introduced, which simulate the wind vibration of round cross-section rod via the test, and gain some effect to reduce the vibration.
