【Abstract】 Indexes of rate of the energy change are defined in this paper, a discussion is made on the influence of the friction coefficient on these indexes of sliding base isolated structure subject to harmonic excitations. Based on the study of these energy indexes, the change rule of the differences between the relative energy input and the absolute energy input of the system with friction coefficient are analyzed, thus, the theoretical basis for further study has been set up.更多还原
