研制了一种摩擦力减震装置。本文通过人工地震波激振试验，研究了该装置减震系统的基本特性。与输入波相比，该系统的峰值加速度幅度已降低至约50-90%。虽然在该系统的固有周期0.5Hz的频率附近识别出谱峰，但是使用具有高摩擦力的轴承降低了谱峰的值。这种装置对于减小地震反应是有用的。
A new device of reduction for seismic response using friction force was developed. In this paper, fundamental characteristics of reduction system for seismic response using this device were investigated by excitation experiment using artificial seismic waves. The peak acceleration amplitude on this system has decreased to about 50-90% over the input waves. Although a spectral peak around the frequency of 0.5Hz that is the natural period of this system was identified, the value of a spectral peak was decreased using bearings with the high friction force. This device is useful for reduction of seismic response.
