Vibrations of blades couple connected by slip-stick dry friction
Original language description
The reduction of enormous great resonance vibrations of turbine blades is very often realized by using dry friction contacts between vibrating elements. Many theoretical, numerical and experimental investigations of dynamic properties of turbine blades were done also in Institute of Thermomechanics ASCR particularly with the main attention on the development of means for reduction of dangerous resonance amplitudes of blades. The dynamic systems investigated in previous papers were two-blades-models connected either by a rubber element, by direct friction contact or by inserted friction element. Prepared paper describes a mathematical model for analysing the dynamic characteristics of two-blades bunch with more complicated stick-slip damping connectionsamong blades than previously used friction characteristics. Several types of stick-slip mathematical models are presented and analysed. Effects of tangential micro-deformations in contact surfaces as well as of dry friction forces and ex
