Description

Technical Field

[0001] The utility model relates to the relevant field of friction pendulum seismic isolation bearings, in particular to a friction pendulum seismic isolation bearing. Background Art

[0002] The friction pendulum vibration isolation support is mainly composed of an articulated slider and an arc sliding surface. There is friction material between the slider and the sliding surface. When the horizontal force is less than the static friction between the slider and the sliding surface, there is no relative deformation between the slider and the sliding surface. The support participates in the force as a whole, and the horizontal stiffness is relatively large. When the horizontal force is greater than the static friction, the support begins to slide. The horizontal force of the support is the resultant force of the dynamic friction generated by the sliding surface and the restoring force generated by the slider swinging along the sliding surface. While sliding, the slider and the sliding surface do work to overcome the friction and consume energy.
