Research about Rolling Friction Pendulum Seismic Isolation System on Ellipse Track

Abstract:

A theoretical analyzing approach about a class of seismic isolation system RFPS (Rolling Friction Pendulum System) is presented.. It starts from the Lagrange equation in multiply body dynamics. This system consists of a roller which is placed in the vicinity of two ellipse concave slides. Computation results for ellipse slide show that it has the three kinds of necessary functions required for an effective isolation system. The relatively long vibration period provides the necessary isolation capability, the gravity provides the reposition capability, and the friction couple, formed with the rolling friction forces at the contacting surface on the top and bottom plate respectively, provides the energy dissipation capability. The evaluation results for a practical building model shows that RFPS has a satisfactory seismic isolation effect.
