Abstract
This paper presents an experimental validation of a proposed non-linear damping model for shaft torsional vibration studies, compared to the linear viscous damping model. Nine different shaft configurations were used. The deflection of each shaft exhibiting free vibration was measured for a period of one minute and the signal component at the natural frequency of torsion was found. The experiments showed that the internal shaft damping was highly non-linear. The damping tended to be not only stiffness related but also depended on the material used.
