... 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...

... vibrational modes 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 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...
