Inter-slip damping of twisted blades in opposed bundles under rotation
Original language description
This paper presents the numerical and experimental solutions of inter-slip damping of twisted blades in opposed bundles. The numerical approach is based on a space finite element model which presents three twisted blades connected by dry friction couplings in their heads. The couplings are considered to be surface-to-surface contacts with friction. The damping effect is evaluated from the free attenuation after a resonant vibration. The resonant vibration of the blades was excited by pulses of a singleelectromagnet during the experiment. The responses of the blades were measured by strain-gauges with a slip-ring signal transmission at rotation. The dynamic behaviour of the blades and the results of damping are in a good accordance with the numerical modelling.
