【Abstract】 The rolling friction energy principle of RFPS isolation system has been expounded in this paper.The non-linear differential equation is derived according to the theorem of kinematic energy and the theory of multiply body dynamics.The solving program which made by Newmark–β method is based on MATLAB.The dynamic response of the equation of six level frame structure under earthquake effect is calculated.The isolation performance of the roller friction isolation system is analyzed.Through comparing with the Isolation performance of the structure of with no isolation bearings and then evaluate its isolation effect.更多还原
