【摘要】 为实现TLD对结构的轻量化振动控制并提升传统TLD的减震性能，提出将附加阻尼网的斜底式调谐液体阻尼器（damping net and sloped-bottom tuned liquid damper,DNS-TLD）与齿轮齿条型惯容装置组合，形成一种新型调谐液体惯容系统（damping net and sloped-bottom tuned liquid inerter system, DNS-TLIS）。在分析DNS-TLIS减振机理的基础上，推导出DNSTLIS的基频求解公式，构建DNS-TLIS-单自由度结构系统力学模型，提出一种等效液体运动速度的求解方法，并依此提出一种简便估算DNS-TLIS总等效阻尼比的方法。通过单层钢框架振动台试验验证该理论模型与总等效阻尼比计算公式的准确性。振动台试验与理论结果表明：DNS-TLIS可以在地震作用下实现较好的结构减震控制效果并完成调谐液体质量的轻量化设计目标，各类TLD中DNS-TLIS的减震性能最为突出，所需实际液体质量最小，工程适用性最佳。更多还原

【Abstract】 In order to realize the lightweight vibration control of TLDs on structures and to improve the damping performance of traditional TLDs,we proposed to combine the damping net and sloped-bottom tuned liquid damper(DNS-TLD) with the rack-and-pinion inerter device to form a new type of tuned liquid inerter system(DNS-TLIS). On the basis of analyzing the damping mechanism of DNS-TLIS,the fundamental frequency solution formula of DNS-TLIS is derived, the mechanical model of DNS-TLIS-single-degree-of-freedom structural system is constructed,and a solution method of equivalent liquid motion velocity is proposed,and accordingly,a calculation method of estimating the total equivalent damping ratio of DNS-TLIS is proposed. The accuracy of the theoretical model and the calculation formula of the total equivalent damping ratio is verified by shaking table tests on a single-story steel frame. The shaking table tests and theoretical results show that DNS-TLIS can achieve excellent structural damping control under seismic action and accomplish the lightweight design goal of tuned liquid mass,and among all types of TLDs,DNS-TLIS has the most outstanding damping performance,requires the smallest actual liquid mass,and has the best engineering applicability.更多还原
