This paper presents a theoretical study of the process of damping of non-linear vibrations in a one-mass model of a mechanical system over a friction damper. The problem is considered on the assumption of a uniform unit pressure distribution between the contacting surfaces of the friction rings. The steady-state motion of the system is subject to harmonic excitation. The analysis includes the following: the influence of the geometric parameters of the system, its external load amplitude, unit pressures and friction coefficient upon the amplitude-frequency characteristics and the phase-frequency characteristics. Structural friction has been also taken into account. The equation of motion of the examined mechanical system has been solved by means of the slowly varying parameters (Van der Pol) method and digital simulation method.
