Discussion of “Contact Unloading Behaviors of Elastic-Power-Law Strain Hardening Material Considering Indenter Elasticity Effect” (Chen, C., Wang, Q., Wang, H., Ding, H., Hu, W., Xie, W., Weng, P., Jiang, L., and Yin, X., 2022, ASME J. Tribol., 144(12), p
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The readers ought to be aware of some claims based on unfounded theories in the subject paper [1], which could possibly distort results and hinder future research and development. To start, Eq. (3) in the subject paper is ...
Dynamic Sensitivities to Fractal Machine Noises in a Mechanical Face Seal
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Mechanical face seals are wide spread in many applications of powered equipment and turbomachinery. Often machine vibration and noise are unavoidable because of changing conditions which can be persistent and forceful. In ...
Exact Spectral Moments and Differentiability of the Weierstrass-Mandelbrot Fractal Function
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fractal mathematics using the Weierstrass-Mandelbrot (WM) function has spread to many fields of science and engineering. One of these is the fractal characterization of rough surfaces, which has gained ample acceptance in ...
Gyroscopic 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 ...
Discussion: “A Numerical Study of the Stable Dynamic Behavior of Radial Face Seals With Grooved Faces” (Person, V., Tournerie, B., and Frêne, J., 1997, ASME J. Tribol., 119, pp. 507–513)
Publisher: The American Society of Mechanical Engineers (ASME)
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: “Stochastic Characterization of Macro- and Microerrors of Journal Bearing Roundness” (Velsher, B., Osman, M. O. M., and Sankar, T. S., 1977, ASME J. Eng. Ind., 99, pp. 327–334)
Publisher: The American Society of Mechanical Engineers (ASME)
Discussion: “Effect of Frequency Excitation on Force Coefficients of Spiral Groove Gas Seals” (Zirkelback, N., San Andrés, L., 1999, ASME J. Tribol., 121, pp. 853–861)
Publisher: The American Society of Mechanical Engineers (ASME)
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: in subcritical speeds only that the harmonics will occur at integer multiples of the rotational speed. This has been observed by Lee and Green 2 in experiments of a flexibly mounted rotor face seal (the association with journal...
Bénard Convection in the Presence of Vertically Varying Exchange Processes
Publisher: American Meteorological Society
Abstract: The Bénard convection problem is examined using a geophyisical model in which the eddy coefficients of viscosity and heat conductivity vary linearly with depth. For variations corresponding to measured coefficients, the ...
