【摘要】 以调谐质量阻尼器为基本模型,设计了适合塔器应用的环形阻尼器。探究质量比、频率比和阻尼比对减振效果影响,并以某在役大高颈比塔器为例,选取质量为0.3t,频率比为1,阻尼比为0.1的环形阻尼器,通过有限元模拟的方式验证其减振效果。研究工作为调谐质量阻尼器在化工行业的应用提供了一定的参考。更多还原

【Abstract】 Designed a ring damper for tower applications taking the tuned mass damper as the basic model.Investigated the effects of mass ratio,frequency ratio and damping ratio on damping effect.Take a large high-necked tower in service as an example,selected the mass of 0.3 t,the frequency ratio of 1,the damping ratio of 0.1 ring dampers.And the damping effect is verified by finite element simulation.The research work provides a reference for the application of tuned mass damper in the chemical industry.更多还原
