Mobility and Impedance Definitions for Plain Journal Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A list of mobility and impedance definitions is given for a set of full-journal-bearing solutions, including the finite-length-bearing solution.
Design Charts for Optimum Bearing Configurations: 1—The Full Journal Bearing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a new design chart for the full journal bearing using dimensionless groups containing all relevant parameters the designer is mainly interested in. Some illustrative examples ...
Design Charts for Optimum Bearing Configurations: 2—The Pivoted-Pad Thrust Bearing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As a followup to an earlier paper in which a new type of design chart for full journal bearings was given a complete set of design charts for pivoted-pad thrust bearings (Michell bearings) ...
Frictional Heating of Tribological Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Wherever friction occurs, mechanical energy is transformed into heat. The maximum surface temperature associated with this heating can have an important influence on the tribological behavior of ...
Journal Bearing Impedance Descriptions for Rotordynamic Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bearing impedance vectors are introduced for plain journal bearings which define the bearing reaction force components as a function of the bearing motion. Impedance descriptions are developed ...
Mobility and Impedance Tensor Methods for Full and Partial-Arc Journal Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Mobility and impedance tensors are introduced for full journal bearings. These tensors may replace the well known mobility and impedance vectors. Since tensors apply to arbitrary systems of ...
Numerical Simulation of Dynamically Loaded Flexible Short Journal Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A numerical method is proposed for calculating film thicknesses in flexible short journal bearings under dynamic load. The system of elastohydrodynamic integro-differential equations is discretized ...
Starvation in Dynamically Loaded Flexible Short Journal Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A starvation model is incorporated in a previously presented numerical method for calculating film thicknesses inflexible short journal bearings under dynamic load. The system of elastohydrodynamic ...
Discussion: “Nondimensional Presentation of Frictional Tractions in Elastohydrodynamic Lubrication—Part I: Fully Flooded Conditions” (Archard, J. F., and Baglin, K. P., 1975, ASME J. Lubr. Technol., 97, pp. 398–410)
Publisher: The American Society of Mechanical Engineers (ASME)
Dynamically Loaded Pivoted Pad Journal Bearings: Mobility Method of Solution
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The mobility-whirl angle method as introduced by Booker in 1964, has been applied to pivoted pad journal bearings to predict the behavior of a rotor supported in this type of bearing. Both ...
