Dynamic Characteristics and Stability Analysis of Space Shuttle Main Engine Oxygen Pump [PDF]
The dynamic characteristics of the Space Shuttle high pressure oxygen pump are presented. Experimental data is presented to show the vibration spectrum and response under actual engine operation and also in spin pit testing for balancing. The oxygen pump

Rotor vibration caused by external excitation and rub [PDF]
For turbomachinery with low natural frequencies, considerations have been recently required for rotor vibrations caused by external forces except unbalance one, such as foundation motion, seismic wave, rub and so forth.

Symbolical Analysis of RF-Network Problems using Mason’s Rule [PDF]
We briefly review Mason’s rule for the computation of RF-network problems and show its implementation into the software package freeMASON. This tool solves symbolically Mason’s rule for any wave quantity and allows to derive analytical expressions as ...

Instabilities of geared couplings: Theory and practice [PDF]
The use of couplings for high speed turbocompressors or pumps is essential to transmit power from the driver. Typical couplings are either of the lubricated gear or dry diaphragm type design.

Stabilization of aerodynamically excited turbomachinery with hydrodynamic journal bearings and supports [PDF]
A method of analyzing the first mode stability and unbalance response of multimass flexible rotors is presented whereby the multimass system is modeled as an equivalent single mass modal model including the effects of rotor flexibility, general ...

Asymmetries arising from the space-filling nature of vascular networks
Cardiovascular networks span the body by branching across many generations of vessels. The resulting structure delivers blood over long distances to supply all cells with oxygen via the relatively short-range process of diffusion at the capillary level ...

induction motor, unbalance, electrical loss, finite element method.
This paper shows the pattern of a 7.5 kW squirrel-cage induction motor’s electrical loss in balanced and unbalanced conditions, modelling the motor using the finite element method and comparing the results with experimental data obtained in the ...
