【摘要】 介绍了采用不同液体(净化水、ZnSO4溶液、甘油溶液)和不同构造措施(设格栅、分隔板或浮板)的调频液体阻尼器(TLD)的振动试验,分析了液体晃动的频率、阻尼比及其对TLD减振性能的影响.根据流体动力学理论,建立了普通圆柱形TLD中晃动液体的势流场.并从晃动液体的动力效应等效原则出发,导出了晃动液体的等效力学模型,讨论了其适用范围

【Abstract】 Vibration tests of tuned liquid damper (TLD) with different liquid (purified water, glycerine solution, ZnSO4 solution) and different constructions (grille, dividing panel, floating soft plate) are carried out. Based on experimental results, the dynamic properties of TLD such as frequency and damp ratio of liquid sloshing are calculated and analyzed. And from hydraulic mechanics theory, the potential function of sloshing liquid in ordinary cylindrical TLD is established. According to the equivalent principle of dynamic effect of sloshing liquid, the equivalent mechanical model is set up, the basic calculation formula is derived. Its application scope is also discussed.
