الوصف: International audience ; To reduce the risk of fatigue problems and flutter phenomena, the structuraldamping of turbomachinery components is increased by integrating constrainedviscoelastic patches into rotating composite blades. However, the temperature,the frequency (of the vibration mode to be damped) and the rotation speed areall parameters which may affect significantly the efficiency of the viscoelasticdamping treatment.In the presented work, a numerical tool is developed to predict the structuraldamping of a dynamic rotating composite fan blade while varying the temperatureand the rotation speed. This study is based on a finite element model of afan disk sector equipped with constrained viscoelastic patches. This work willallow quantifying the influence of temperature and rotation speed on the efficiencyof the passive damping treatment and contribute to the design of higherperforming blades.
