“…Chen and Semercigil (1993) proposed an impact damper to attenuate transient vibrations of light structures such as beams simulating robot arms. This problem has attracted considerable attention, as evident in the works of Sinha (1988) and Yamuara and Ono (1989). Bapat and Sankar (1984) investigated the performance of a simple single unit impact damper in free and forced vibration.…”

We present a numerical study for the suppression of self-excited vibrations represented by a Rayleigh oscillator using an impact viscous damper. A systematic approach based on a univariate search optimization method is used to determine the best design parameters for suppressing self-excited vibrations. The suggested system is found to be effective in suppressing this type of vibration. Optimum parameters for complete quenching of such vibrations are obtained. We investigate quasi-static as well as dynamic variations of the bifurcation parameter for both supercritical and subcritical Hopf bifurcation.
