Measurement of Hydrodynamic Interaction Matrices of Boiler Feed Pump Impellers
(The American Society of Mechanical Engineers (ASME), 1987)For rotordynamic calculations on multistage pumps, one must know–among other things–the hydrodynamic forces generated by a vibrating impeller. In linearized form these forces may be described by ... -
Trends in Eigenvalues of Straight and Bent Beams on Elastic Supports
(The American Society of Mechanical Engineers (ASME), 1987)Singular value analysis is used to develop eigenvalue and eigenvector trends for beams supported by periodically-spaced, elastic elements. These trends are illustrated for both straight and bent ... -
Dynamic Response of a Radial Beam With Nonconstant Angular Velocity
(The American Society of Mechanical Engineers (ASME), 1987)The effects of a nonconstant angular velocity upon the vibration of a rotating Euler beam are investigated. It is assumed that the angular velocity can be written as the sum of a steady-state ... -
Random Vibrations Due to Small-Scale Turbulence With the Coherence Integral Method
(The American Society of Mechanical Engineers (ASME), 1987)Conventional methods exist for obtaining the random vibration response of a finite-element model to “large-scale” turbulence, such as gust loading on an aircraft. However, this loading is random ... -
Two-Plane Balancing of a Rotor System Without Phase Response Measurements
(The American Society of Mechanical Engineers (ASME), 1987)This paper presents, and experimentally verifies, a two-plane balancing technique for rigid rotors and possibly flexible rotors operating at a constant speed. The technique, based upon influence ... -

Numerical Simulation of Acoustic Agglomeration and Experimental Verification
(The American Society of Mechanical Engineers (ASME), 1987)Acoustic agglomeration is proposed as an intermediate treatment in the flue gas cleanup train of the effluents from coal burning power plants. Acoustic agglomeration causes the micron and submicron ... -
Optimal Placement of Critical Speeds in Rotor-Bearing Systems
(The American Society of Mechanical Engineers (ASME), 1987)The design of a rotor-bearing system is an iterative process in which the parameters that influence the design are modified until the desired design objectives are achieved. Primary among the ... -
An Approximate Explicit Solution for Polar Strain of Hydraulically Bulged Circular Diaphragms
(The American Society of Mechanical Engineers (ASME), 1987)Requirements for practical bulging tests of sheet metals favor small die aperture and surface extensometry with relatively large gage length. The practice of equating the meridional strain at ... -
On the Vibration Damping of a Plate by Means of a Viscous Fluid Layer
(The American Society of Mechanical Engineers (ASME), 1987)Vibration damping of a plate by means of a fluid layer is investigated. First, the frequency-dependent flow resistance of a fluid layer is explained with a simple illustration of the damping ... -
