在这项研究中，我们提出了一种新的地震控制装置，调谐粘滞质量阻尼器（TVMD），建筑系统。我们给出了一个使用滚珠丝杠机构，这是实现新的设备的最重要的组成部分之一的表观质量放大器的详细描述。我们还推导出一个封闭形式的解决方案的最佳抗震控制设计的单自由度结构受到谐波激励。并与传统的粘滞阻尼器和粘滞质量阻尼器系统进行了性能比较。对于具有相同附加阻尼系数的阻尼器的线性结构系统，使用TVMD的振动控制系统是最有效的。通过分析和振动台试验验证了TVMD在地震激励下的有效性。版权所有（c）2011约翰威利父子有限公司
In this study, we propose a new seismic control device, tuned viscous mass damper (TVMD), for building systems. We give a detailed description of an apparent mass amplifier using a ball-screw mechanism, which is one of the most important components for realizing the new device. We also derive a closed-form solution of an optimum seismic control design for a single-degree-of-freedom structure subjected to harmonic excitation. The performance of the new device is compared with those of the conventional viscous damper and viscous mass damper systems. The vibration control system using the TVMD is shown to be the most effective for linear structural systems with dampers having the same additional damping coefficient. The effectiveness of the TVMD for seismic excitation is verified by analyses and shake table tests with a small-scale TVMD. Copyright (c) 2011 John Wiley & Sons, Ltd.
