【摘要】 利用Housner提出的集中质量法建立了水箱中液体振动的力学模型,得出计算脉冲质量和振荡质量的计算公式;利用悬挂水箱的特点,建立水箱—结构体系的多自由度计算模型,得出了考虑摆长影响的质量和刚度的计算公式;针对所提出模型,定量的分析了各种参数对结构体系减振效果的影响规律;得出几种对工程应用有益的结论.研究的结果表明,水箱的尺寸、摆长、阻尼、质量比、频率比的参数对减振的效果起着重要的作用,合理选取这些参数可以有效减小结构在地震荷载作用下的振动反应.研究的结论为该体系的进一步应用奠定了基础.更多还原

【Abstract】 An effective controller can be made by hanging up the water tank on the upper floor of the structure. The structural responses of building can be controlled by use of the vibration of water in the water tanks and swaying of the pendulums. The effectiveness of the structural control is influenced by the shape of the water tank, the depth and the number of water tank, the length of the pendulum et al. In this paper, the influencing factors of the hanging water tank are analyzed quantitatively by setting up the calculating model of the waterstructure system. The results of the research show that the structural vibrations under earthquake can be reduced effectively by choosing the suitable parameters and lay a basic foundation for the engineering application of the technique in the future.更多还原
