为了实现高层建筑的振动主动控制，提出了一种新型结构的主动质量阻尼器，即由多级橡胶支座支承运动质量。由于这种结构，阻尼器可以安装在建筑物的屋顶上。这意味着阻尼器不需要室内空间。此外，该结构还可以减小质量加速度中的操作摩擦和变形。对于阻尼器的控制，提出了一种变增益控制律，通过该控制律，阻尼器不仅可以抵抗风和弱地震，而且可以抵抗强震，同时将其位移保持在液压致动器的行程限制内。对阻尼器的实验模型进行了激振试验，其中5300 kg的质量由4个多级橡胶支座支撑，并由2个液压致动器在水平方向上控制。通过试验和仿真研究，验证了该结构和控制律对高层建筑振动主动控制的有效性。
An active mass damper with a new structure was developed to implement active vibration control for tall buildings, in which a moving mass is supported by multistage rubber bearings. Because of this structure, the damper can be installed on the roof of the building. This means that no indoor space is needed for the damper. Furthermore, the structure can reduce the operational friction and distortion in the mass acceleration as well. For control of the damper, a variable gain control law was proposed, by which the damper can perform against not only winds and weak earthquakes but also strong earthquakes, while it keeps its displacement within a stroke limit of the hydraulic actuators. Excitation tests were carried out for an experimental model of the damper in which a 5300 kg mass was supported by 4 multistage rubber bearings and controlled by 2 hydraulic actuators in a horizontal direction. Through the tests and simulation studies, it was confirmed that the structure and the control law were effective for active vibration control of tall buildings.
