附加阻尼网的斜底式TLD减震控制理论与试验研究OA北大核心CSTPCD
Theoretical and experimental study on damping net and sloped-bottom tank tuned liquid damper with damping control
为解决传统调谐液体阻尼器(tuned liquid damper,TLD)中有效阻尼偏小、用水量偏大等问题,提出一种附加阻尼网的斜底式水箱调谐液体阻尼器(damping net and sloped-bottom tuned liquid damper,DNS-TLD),将水箱底面倾斜的TLD与阻尼网有机结合,强化水箱内液体晃动,可提供更大附加阻尼比并降低用水量.建立了附加DNS-TLD结构的力学模型,阐述其减震机制,提出了一种简便估算DNS-T…查看全部>>
The conventional tuned liquid damper(TLD)has limitations such as low effective damping and high water storage.A damping net and sloped-bottom tank tuned liquid damper(DNS-TLD)was proposed.By combining the sloped-bottom tank TLD with a damping net,strengthening liquid sloshing in the tank,the damping ratio was enhanced and the water storage was reduced.A controlled structural mechanical model of the DNS-TLD was proposed to illustrate its damping mechanism.A s…查看全部>>
