Dynamic Simulation Of Centrifugal Compressor Systems
(Texas A&M University. Gas Turbine Laboratories, 1977)
The capacity, pressure, speed and horsepower of centrifugal compressors have been trending higher and higher in the past few years. Not only are machine designers faced with increasing aerodynamic and mechanical problems, ...
High-Speed Gear Vibration And Noise Experience
(Texas A&M University. Gas Turbine Laboratories, 1977)
High-speed gear pinion precession-shuttling and noise, caused by overhanging weight of the coupling and by misalignment forces generated by tooth friction in the coupling, are being controlled by reduced bearing clearances. ...
Dynamic Characteristics Of Fluid-Film Bearings
(Texas A&M University. Gas Turbine Laboratories, 1977)
The concept of cross-coupling in bearings is introduced and its influence on bearing dynamics is presented. Procedures for obtaining cross-coupled spring and damping coefficients are explained. The special case of pad pitch ...
