ASME ( American Society of Mechanical Engineers )
Description: The American Society of Mechanical Engineers (ASME) is a professional association that, in its own words, "promotes the art, science, and practice of multidisciplinary engineering and allied sciences around the globe" via "continuing education, training and professional development, codes and standards, research, conferences and publications, government relations, and other forms of outreach." ASME is thus an engineering society, a standards organization, a research and development organization, a lobbying organization, a provider of training and education, and a nonprofit organization. Founded as an engineering society focused on mechanical engineering in North America, ASME is today multidisciplinary and global.

Turborotor Instability: Effect of Initial Transients on Plane Motion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The rigid-body dynamics of rotors supported in plain, cylindrical, cavitated, fluid-film journal bearings are investigated numerically by Runge-Kutta extrapolation techniques. Expressions for journal ...
The Potential Impact of Multiplane-Multispeed Balancing on Gas Turbine Production and Overhaul Costs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes recent advances in the development of a practical, cost-effective method for balancing, in a single step, a final shaft-bearing assembly simultaneously in a number of planes ...
Rigid-Body Rotor Dynamics: Dynamic Unbalance and Lubricant Temperature Changes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The case of a symmetric rotor supported on two identical, rigidly mounted, self-aligning, finite-length (L/D = 1) fluid-film journal bearings is considered. Rotor position is described by two ...
Suppression of Rotor-Bearing System Vibrations Through Flexible Bearing Support Damping
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A bearing damper, operating on the support flexure of a pivoted pad in a tilting-pad type gas-lubricated journal bearing, has been designed, built, and tested under externally applied random ...
Experimental Evaluation of Multiplane-Multispeed Rotor Balancing Through Multiple Critical Speeds
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experimental tests have been conducted to further demonstrate the ability of the Influence Coefficient Method to achieve precise balance of flexible rotors of virtually any design for operation ...
Discussion: “Experimental Rotor Unbalance Response Using Hydrostatic Gas Lubrication” (Dayton, R. D., and Chasman, M. R., 1973, ASME J. Lubr. Technol., 95, pp. 469–476)
Publisher: The American Society of Mechanical Engineers (ASME)
Dynamic Stability of Gimbaled Spiral-Grooved Thrust Bearing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A general, easily implemented technique is developed by which stability maps may be determined for gimbaled, gas-lubricated, spiral-grooved thrust bearings. This technique is based upon the spectral ...
Application of an Advanced Hybrid Rotordynamics Model to the Complete Structure of a Marine Gas Turbine Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Extensive fleet experience with the LM2500 marine gas turbine engine has identified it as an engine that exhibits wear-accelerating vibration effects. The critical speeds and associated mode ...
Reduction of Vibration and Noise Generated by Planetary Ring Gears in Helicopter Aircraft Transmissions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Rotor-drive gearboxes are major noise sources in helicopter aircraft. Narrow-band examination of this noise often indicates the presence of several or more very high, narrow noise peaks, which ...
Flexible Rotor Balancing by the Exact Point-Speed Influence Coefficient Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A test program was conducted to confirm experimentally the validity of the exact point-speed influence coefficient method for balancing rotating machinery, and to assess the practical aspects of ...
