The centrifugal pendulum as a non linear torsional vibration absorber

Abstract

In this paper we study the centrifugal pendulum as a torsional vibrations absorber of an engine. A non-autonomous two degrees of freedom mechanical system with viscous-Coulomb damping is considered. The motion equations are written and we analyse for small oscillations of the pendulum, the effect of the non linear damping on the response curves in amplitude. Several numerical examples are ratio μ and the damping coefficients on the resonance peaks.
