摘　　要： 为增大调谐液体阻尼器(TLD)中液体的晃动质量,以获得更优的动力特性,首次提出内置横向圆柱体TLD(TLD embedded a transverse cylinder,简称TLDETC)的概念。结合流体力学原理以及能量方法推导了TLDETC的晃动质量、晃动力、晃动阻尼比以及晃动频率的表达式,并通过三种设置方案对TLDETC与普通TLD进行了动力特性的对比分析。推导结果表明,TLDETC有效地增大了液体的晃动质量;而分析结果表明,TLDETC具有比普通TLD更优的动力性能。 A new tuned liquid damper(TLD) device-a TLD with an embedded transverse cylinder(TLDETC) was presented to obtain greater sloshing force and more excellent dynamic characteristics.The sloshing mass,sloshing force,sloshing damping ratio and sloshing frequency of a TLDETC were deduced by using fluid mechanics principle and energy method.Then,the comparison analysis on dynamic characteristics of a TLDETC and an ordinary TLD was made through three setting schemes.The results showed that the sloshing mass was effectively increased in TLDETC,and the dynamic performance of TLDETC was better than that of ordinary TLD.
