A Review of Friction Damping of Turbine Blade Vibration

This paper reviews recent research on analyzing and designing friction dampers to reduce turbine blade vibration. It discusses previous literature reviews, methods of analysis, models of friction constraint , methods of modelling the structural aspects of the system, procedures for optimizing the damper 's design, and some research on related problems. The author a t t empts to indicate some of the limitations and advantages of the cited methods. Conclusions are drawn concerning the current state-ofthe-art and recommendat ions are made regarding directions for fu ture research and development.
