Source Identification Using Multi-Input/Single-Output Modeling and Causality Checking of Correlated Inputs
(The American Society of Mechanical Engineers (ASME), 1994)This paper presents experimental results of a case study of source identification using multiple-input/single-output modeling in a case where the inputs are coherent to some extent and, hence, ... -
Dynamic Response of Spinning Blades Subjected to Gyroscopic Motion
(The American Society of Mechanical Engineers (ASME), 1994)This paper presents an investigation into the vibration and stability of a blade spinning with respect to a nonfixed axis. Due to the motion of the spin axis, parametric instability of the ... -
Stability of Sliding Frictional Surfaces with Varying Normal Force
(The American Society of Mechanical Engineers (ASME), 1994)This paper presents the stability analysis of a single degree-of-freedom elastic system following a rate-and state-dependent friction law. Normal force is assumed to depend on the displacement, ... -
A Substructural Control Technique for High-Order Systems
(The American Society of Mechanical Engineers (ASME), 1994)A substructural control technique consisting of local and global controllers is proposed for high-order systems. The global controllers are used to minimize the effect of coupling between ... -
An Improved Theoretical Model of Acoustic Agglomeration
(The American Society of Mechanical Engineers (ASME), 1994)An improved theoretical model is developed to describe the acoustic agglomeration of particles entrained in a gas medium. The improvements to the present theories are twofold: first, wave ... -

Bending and Shear Damping in Beams: Frequency Domain Estimation Techniques
(The American Society of Mechanical Engineers (ASME), 1994)In this paper we consider damping mechanisms in the context of dynamic beam models. We summarize previous efforts on various damping models (strain rate or Kelvin-Voigt, time hysteresis (Boltzmann), ... -
Vibration of an Eccentrically Clamped Annular Plate
(The American Society of Mechanical Engineers (ASME), 1994)Small amplitude vibration of an eccentric annular plate, which is free along its outer edge and clamped along the interior, is investigated through experimental and analytical methods. A disk ... -
Accelerating Load on a Rotating Rayleigh Beam
(The American Society of Mechanical Engineers (ASME), 1994)The response of a rotating Rayleigh beam subjected to an axially accelerated distributed surface line load is studied. Clamped-clamped, clamped-pinned, and clamped-free support conditions and four ... -
Higher Harmonic Oscillations in a Noncontacting FMR Mechanical Face Seal Test Rig
(The American Society of Mechanical Engineers (ASME), 1994)In order to investigate experimentally the dynamic behavior of a noncontacting flexibly mounted rotor (FMR) mechanical face seal a test rig was designed and built. Test results showed that the ... -
