RISStability, Load Capacity, Stiffness, and Damping Advantages of the Double Pocket Journal Bearing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The double pocket bearing design is discussed and compared to the plain three axial groove bearing. Rigid rotor stability, load capacity, and stiffness and damping curves are shown for the two ...

Four Pad Tilting Pad Bearing Design and Application for Multistage Axial Compressors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The advantages of operating multistage axial compressors on 4 pad tilting pad bearings are discussed and compared to other fixed bore and tilting pad bearing designs. These advantages include ...
Effect of Residual Shaft Bow on Unbalance Response and Balancing of a Single Mass Flexible Rotor—Part I: Unbalance Response
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of residual shaft bow on the unbalance response of a single mass rotor on rigid supports has been examined with a theoretical analysis. The analysis determined the amplitude, phase ...
Effect of Residual Shaft Bow on Unbalance Response and Balancing of a Single Mass Flexible Rotor—Part II: Balancing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Three methods of balancing a rotor with a residual shaft bow were presented. Method I balanced the total shaft amplitude to zero at the balance speed. Method II balanced the elastic deflection ...
Systems of Finite Elements for Finite Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Systems of finite elements are organized using matrix notation for finite length bearings. Most fluid film bearings have surface areas which can be divided into a grid of elements whose nodes ...
Experimental-Theoretical Comparison of Instability Onset Speeds for a Three Mass Rotor Supported by Step Journal Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Theoretically predicted instability onset speeds are compared to the experimental instability threshold speeds for a simple three mass flexible rotor supported by five geometrically different sets ...
Analysis and Identification of Subsynchronous Vibration for a High Pressure Parallel Flow Centrifugal Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The evaluation of turbomachinery designs prior to actual hardware test and field installation is now the rule rather than the exception for rotating machinery manufacturers. This requires the ...
