新式调谐液体阻尼器的进展研究(英文)

Recent Advances in TLD Research

介绍并分析了六种新颖的调谐液体阻尼器(TLD)。其中斜底式TLD、附加磁性流体式TLD(TMFD)与圆锥式TLD设计的主要目的是优化TLD中液体的晃动力;内表面带凹槽的TLD(WSDE)与带夹板网筛的TLD设计的主要目的是增加水箱内液体的耗能;带挡板式TLD设计的主要目的则是拓宽TLD的有效频率带宽。此外,提出了一种可控式TMD-TLD混合调频系统(controllable TMD-TLD hybrid system,CTTHS);而CTTHS能够保证结构物在工程振动中出现频率偏移时的减振效果。

Six novel types of tuned liquid dampers （TLD） is presented, in which sloped bottom tuned liquid damper, tuned magnetic fluid damper （TMFD） and conical tuned liquid damper are mainly designed to optimize the control force for reducing structural vibrations; while the water sloshing damper with embossments （WSDE） and tuned liquid damper with slat screens are mainly designed to increase energy dissipation inside the liquid filled tank; and tuned liquid damper with baffles is designed to broaden the effective frequency spectrum of the tuned damper system. Further, a controllable TMD-TLD hybrid system （CTI＇HS） is also developed herein. The CTTHS is capable of guaranteeing the reduction effect of a structure in case structural frequency excursion happened in engineering vibration.
