Friction pendulum vibration isolation device with vertical gravity tuning unit
The invention discloses a friction pendulum vibration isolation device with a vertical gravity tuning unit, and belongs to the technical field of vibration reduction and vibration isolation. The problems that in the prior art, starting sensitivity is low, the friction coefficient cannot adjusted, and start force is large are solved. The device can achieve stable vibration isolation on pulse type seismic motion, long-period seismic motion and seismic motion of other traditional vibration isolation devices weak in vibration isolation effect. According to the technical essentials, vibration isolation units are arranged between an upper plate and a lower plate; vertical supporting portions are fixedly supported on the ground, and the upper ends of the vertical supporting portions are mounted on the bottom face of the lower plate; and a gravity tuning portion is arranged in the vertical supporting portion, and the upper end of the gravity tuning portion is fixedly connected with the upper plate. Each vibration isolation unit comprises a lower sliding portion, a changeover sliding block and an upper connecting block, all of which are in contact, and no fixing measures are adopted. By means of the gravity tuning portion, the vibration isolation amplitude and stability of the device can be remarkably enhanced, the gravity tuning portion is only influenced by the radius of the frictionpendulum arc face, and the device is especially suitable for seismic protection of floating cultural relics, precision equipment and the like.
一种带竖向重力调谐单元的摩擦摆隔震装置，属于减震隔震技术领域。解决了现有技术启动灵敏度较低，摩擦系数不可调，启动力较大的问题；并且，本装置可以实现对脉冲型地震动，长周期地震动等传统隔震装置隔震效果较弱的地震动的稳定隔震。技术要点：隔震单元置于上板与下板之间；竖向支撑部固定支撑于地面上，竖向支撑部上端安装于下板的底面上；重力调谐部置于竖向支撑部内部，上端与上板固定连接。隔震单元包括下部滑动部、转换滑动块及上部连接块，三个构件之间相互接触，且没有固定措施。本发明的重力调谐部可以显著增强本装置的隔震幅度及稳定性，重力调谐部仅受摩擦摆弧面半径的影响，本发明尤其适用于浮放的文物、精密设备等的地震保护。
