It has been stated that the Suspensions with indirect damping by linear spring are more effective in isolating shocks and chatterings. In this paper, one type of such suspensions, to which the Coulomb friction damper is applied, is considered, and the nature of the steady vibrations when its main mass is subjected to a harmonic exciting force, consisting of two different vibrations connected by boundary conditions, is clarified by a rigorous procedure. As a numerical example, the amplitudes of the vibrations in the case where the ratio of spring constant κ=1,are compared with those obtained from the approximate solutions by the equivalent viscous damping method, the result of which shows that there exist considerable differences in the neighbourhood of a fixed point independent of the damping, and that the equivalent viscous damping method must be used with full knowledge of this fact in such a case.
