On e cient and adaptive modelling of friction damping in bladed disks
High cycle fatigue failure of turbine and compressor blades due to resonance in the operating frequency range is one of themain problems in the design of gas turbine engines. To suppress excessive vibrations in the blades and prevent high cycle fatigue, dry friction dampers are used by the enginemanufacturers. However, due to the nonlinear nature of friction contact, analysis of such systems be...
متن کاملCracking-Induced Mistuning in Bladed Disks
A study of the mechanisms of cracking-induced mistuning in bladed disks is presented in this paper. An analytical model for a bladed disk was formulated using lumped-mass-beams, and a cracked blade was represented by a beam with a through-crack at the root. Local stiffness reduction due to cracking was incorporated using a flexibility matrix method. The dynamic characteristics of the bladed dis...

متن کاملValve's dynamic damping characteristics - Measurement and identification
This paper proposes a novel method to test the dynamic damping characteristics of valve. The testing system employs the vertical movement pattern, and has a suspension support structure. Force sensors are installed to measure the dynamic friction of the working valve directly. Making use of LuGre friction model and both adaptive genetic algorithm and chaos particle swarm optimization algorithm,...
متن کاملUncertainty quantification in nonlinear structural dynamics for mistuned bladed disks
The recent improvements in turbomachinery design combined to the unavoidable requirements of kerosene savings require to analyze the exceptional operating regime of bladed disks, for which large deformations and large displacements can occur. It seems then quite appropriate to consider the geometrically nonlinear effects in the computational models dedicated to the analysis of mistuned turbomac...
