...Thorsten Pfister; Philipp Günther; Florian Dreier; Jürgen Czarske Monitoring rotor deformations and vibrations dynamically is an important task for improving both the safety and the lifetime as well as the energy efficiency of motors and turbo machines. However, due to the high rotor speed...

... of the injector, such as control valve, needle, and pressure rod were modeled using the mass–spring–damper scheme. The axial deformation under pressure of needle, pressure rod, nozzle and injector body was modeled. This effect was found to also affect the control valve device operation, and was properly accounted...

... deformation eigenvalues and eigenfunctions finite element analysis Dynamic analyses of bladed disks or blisks found in turbomachinery rotors typically involve several idealizations of true conditions. Two such idealizations are of particular interest to the investigation reported in this paper...

... in an approximate way. These approaches, while often sufficiently accurate, are questionable when wheel-shaft coupling is observed or when fluid elements are strongly coupled with local structural deformations (leakage flow between wheel and casing, fluid bearings mounted on a thin-walled shaft, etc.). The approach...

...B. O. Al-Bedoor, Assistant Professor, In this study, a reduced-order nonlinear dynamic model for shaft-disk-blade unit is developed. The multibody dynamic approach with the small deformation theory for both blade-bending and shaft-torsional deformations is adopted. The equations of motion...

...Ufuk Senturk; Rogerio S. Lima; Carlos R. C. Lima; Christopher C. Berndt The deformation behavior of thermally sprayed partially stabilized zirconia (PSZ) coatings are investigated using Hertzian indentation and four-point bend testing, with in situ acoustic emission monitoring. The experimental...
