The governing equation of a rotating flexible disc under stationary sliders is modelled under consideration of the initial transverse runout of the disc. Natural frequency and stability of the system is studied and checked, and steady-state response is obtained. The effects of system parameters on the steady-state amplitude of the sliders are analysed and resonance induced by the sliders is discovered. The decrease of the number of nodal diameters of the initial transverse runout and slider mass, and the increase of disc damping, slider damping, and natural frequency and friction force at the disc—slider interface, can be used to suppress the amplitude.
