Self-excited vibrations of bladed wheel analytical model with nozzle excitation and dry friction damping
Original language description
In this contribution, a bladed wheel with dry friction couplings in tie bosses between neighbouring blades is studied. Bladed wheel is excited by stator nozzle excitation in addition to aeroelastic self-excitation modelled by Van der Pol model. Two types of self-excitation are studied, the first is dependent on absolute motion of each blade, the second on relative motions between neighbouring blade pairs. Results of simulations are shown for both cases for various number of stator blades and friction forces in tie-boss contacts. Damping ability of those contacts are compared.
