Single Surface Friction Pendulum Isolator

The single surface friction pendulum isolator is a new type of dry friction sliding isolation bearing that combines the principles of a sliding bearing and a pendulum. It consists of a spherical main sliding surface and a rotating surface. When the seismic force exceeds the static friction force, displacement is generated through the main sliding surface , causing the superstructure to undergo a simple pendulum motion, extending the structure's natural vibration period and reducing its seismic response. Simultaneously, friction on the main sliding surface dissipates energy, while the rotating surface provides rotation between the upper and lower plates of the bearing. The single-curved friction pendulum bearing utilizes the company's independently developed HSM sliding material, which, compared to traditional materials, offers superior load-bearing capacity, high hysteresis curve stability, long service life, and high-temperature resistance. Conventional bearings have a vertical load-bearing capacity range of 1,000 to 100,000 kN, and higher vertical load-bearing capacity designs can be customized upon request. This product can be used in bridges, buildings, and any other civil engineering structure.

The company's single surface friction pendulum isolator has obtained the European standard EN15129 CE certification.

Typical application cases of the company's single surface friction pendulum isolator:

Domestic: Dayue Expressway, Zhengzhou Nongye Road, Guangzhou Pearl Bay Bridge, etc.

Overseas: Romania ST Expressway and other projects.
