Retrofitting A Large Steam Turbine With A Mechanically Centered Squeeze Film Damper.
(Texas A&M University. Turbomachinery Laboratories, 1999)
Reviewed is the application of a squeeze film damper to a large
steam turbine that addresses high vibration passing through the
first critical speed. The turbine was the fifth near identical machine
purchased over the ...
Shifting Critical Speeds Out Of The Operating Range By Changing From Tilting Pad To Sleeve Bearings.
(Texas A&M University. Turbomachinery Laboratories, 1993)
One property of heavily to moderately loaded sleeve bearings is the resulting asymmetric stiffness and damping coefficients. These asymmetric properties often result in split first critical speeds. Since the horizontal ...
Tilting Pad Journal Bearing Pivot Design For High Load Applications.
(Texas A&M University. Turbomachinery Laboratories, 1995)
Reducing pivot stress, pivot wear and preventing pivot failure are major design challenges encountered by tilting pad bearing designers in the extremely high load regime where the bearing unit load may often range up to ...
Subtracting Residual Unbalance For Improved Test Stand Vibration Correlation.
(Texas A&M University. Turbomachinery Laboratories, 1997)
The importance of correlating rotordynamic analytical results to actual test data has become extremely important in recent years. Many user specifications require the verification of vendor generated analytical results in ...
Tilting Pad Bearing Design.
(Texas A&M University. Turbomachinery Laboratories, 1994)
The basics of tilting pad bearing design are discussed to include limits of operation for load, speed, and metal temperature. Optimum temperature sensor locations are recommended for self-aligning and nonaligning tilting ...
