A theoretical analyzing approach about ERFPS (Eccentric Rolling Friction Pendulum System) is presented. It starts from formulation of the governing equation according to relative kinematics energy theorem in multiply body dynamics. This system consists of an eccentric roller which is placed in vicinity of two circular concave curve slides to form non-indented contacts. Computation results show that it has the three kinds of necessary capabilities required for an effective isolation system. The… Expand
