Abstract: Abstract. This study advances the prediction of vibration response variability arising from the nonuniqueness of static friction forces (residual traction uncertainty) in turbine blades coupled by frictional interfaces. ...

Abstract: This paper addresses two main subjects. First, a novel test setup is described to experimentally study the nonlinear dynamic behavior of a turbine blade coupled with two midspan dampers (MSDs). To this end, a representative ...

Abstract: Abstract. Friction damping devices like tip shrouds are usually employed in low pressure turbine (LPT) blades to reduce their large vibration amplitudes. From an engineering point of view, experimental validation of the ...

Abstract: Friction dampers are one of the most common secondary structures utilized to alleviate excessive vibration amplitudes in turbomachinery applications. In this paper, the dynamic behavior of the turbine bladed disks coupled ...
