调频液体阻尼器(TLD)的等效力学模型研究
STUDY ON EQUIVALENT MECHANICAL MODEL OF TUNED LIQUID DAMPER
【摘要】 本文根据流体力学理论,建立了圆柱形TLD中晃动液体的势流场,并从液体晃动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,并阐明其适用范围。文量计算的结果表明,在工程应用中,仅用TLD的一阶晃动等效力学模型就能满足工程需要。
【Abstract】 he potential function of sloshing liquid in cylindrical tuned liquid damper is established based on hydraulic theory.According to the equivalence principle of dynamic effect of sloshing liquid,the equivalent mechanical model is derived and its application is formulated.Numerical examples show that only the first order equivalent mechanical model is accurate enough to meet the engineering requirement.
