RISGyroscopic and Support Effects on the Steady-State Response of a Noncontacting Flexibly Mounted Rotor Mechanical Face Seal
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The dynamic behavior of a noncontacting rotary mechanical face seal is analyzed. A closed-form solution is presented for the response of a flexibly mounted rotor to forcing misalignments which ...

The Rotor Dynamic Coefficients of Coned-Face Mechanical Seals With Inward or Outward Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The linearized fluid film dynamic coefficients, i.e., stiffness and damping, of flexibly-mounted rotor noncontacting mechanical face seals are found. The coefficients are derived from a previous ...
Discussion: “Operation of Foil Bearings Beyond the Bending Critical Mode” [ASME J. Tribol., 122, No. 1, pp. 192–198 (2000)]1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The author associates the (integer multiple of) harmonics shown in Fig. 19 with rigid body frequencies. Would the author elaborate on this, and perhaps provide a theoretical foundation that ...

Analysis and Optimization of Semicircular and Straight Lobe Viscous Pumps
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A viscous pump design that is capable of producing higher flow rates than a viscous pump previously introduced by Etsion and Yaier (1988) is developed and investigated. The key to the new ...

Dynamic Analysis of a Cantilever-Mounted Gas-Lubricated Thrust Bearing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The dynamic stability of a cantilever-mounted gas-lubricated thrust bearing is analyzed using the step-jump approach. The solution is based on linearization of the equations of motion assuming ...

On the Stability of Gas Lubricated Triboelements Using the Step Jump Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The step jump method was developed approximately three decades ago to help determine the stability of gas lubricated triboelements. In the approach, the force contribution from the gas layer ...
