Nonlinear Vibrations of Low Pressure Turbine Bladed Disks: Tests and Simulations

Nonlinear Vibrations of Low Pressure Turbine Bladed Disks: Tests and Simulations

One of the most effective methods to limit the mechanical vibrations of bladed disks is the use of friction damping at mechanical joint interfaces. Unfortunately, dedicated tests to assess the impact of mistuning and the effectiveness of friction dampers are uncommon. This paper presents an original...
