On the Active-Passive Hybrid Control Actions of Structures With Active Constrained Layer Treatments
(The American Society of Mechanical Engineers (ASME), 1997)This paper is concerned with the analysis of active and passive hybrid actions in structures with active constrained damping layers (ACL). A system model is derived via Hamilton’s Principle, ... -
On the Control of Chaos in Extended Structures
(The American Society of Mechanical Engineers (ASME), 1997)A mechanism is proposed for synchronizing the chaotic vibrations of an externally forced array of oscillators with nearest-neighbor viscoelastic coupling. The proposed mechanism involves the ... -
Modal Sensitivity Analysis of Coupled Acoustic-Structural Systems
(The American Society of Mechanical Engineers (ASME), 1997)Modal analysis of coupled acoustic-structural systems leads to unsymmetric eigenproblem of special form which introduce different left and right eigenvectors. In this paper, the relation between ... -
Noise Transmission Through a Vehicle Side Window Due to Turbulent Boundary Layer Excitation
(The American Society of Mechanical Engineers (ASME), 1997)This paper presents results of an investigation on noise transmission through an aluminum panel clamped to a greenhouse vehicle model subject to random acoustics, random vibration, and turbulent ... -
Complex Time Series Modeling and Analysis for Rotor Dynamics Identification
(The American Society of Mechanical Engineers (ASME), 1997)A new time series method, directional ARMAX (dARMAX) model-based approach, is proposed for rotor dynamics identification. The dARMAX processes complex-valued signals, utilizing the complex modal ... -
An Experimental Investigation of Multimode Responses in a Cantilever Beam
(The American Society of Mechanical Engineers (ASME), 1997)An experimental investigation into the planar, multimode response of a cantilever metallic beam to a transverse harmonic excitation is presented. The cantilever beam was tested in both the ... -
Control of Forced Vibration Using Multi-Electrode Electro-Rheological Fluid Dampers
(The American Society of Mechanical Engineers (ASME), 1997)Vibration control of cylindrical, electro-rheological fluid (ERF) dampers were studied. Single- as well as multi-electrode cylindrical ERF dampers were designed, built and tested under a forced ... -
A Finite Element Geometrically Nonlinear Dynamic Formulation of Flexible Multibody Systems Using a New Displacements Representation
(The American Society of Mechanical Engineers (ASME), 1997)In previous work (Mayo, 1993), the authors developed two geometrically nonlinear formulations of beams inflexible multibody systems. One, like most related methods, includes geometric elastic ... -
A New Class of Distributed Sensors
(The American Society of Mechanical Engineers (ASME), 1997)A new class of distributed sensors is presented which can measure both the linear and angular deflections of composite beams. The sensor relies in its operation on a set of wires which are ... -
Torsional Vibration Control of a Shaft Through Active Constrained Layer Damping Treatments
(The American Society of Mechanical Engineers (ASME), 1997)This paper proposes a hybrid damping design to control torsional vibration of a shaft with a circular cross section through use of actively constrained layer (ACL) damping treatments proposed ... -
Effects of Normal Strain in Core Material on Modal Property of Sandwich Plates
(The American Society of Mechanical Engineers (ASME), 1997)In vibration analysis of sandwich beam/plates, it is often assumed that there is shear deformation only, without extension or compression in the viscoelastic layer. Certainly, this assumption may ... -
Mechanisms of Localized Vibration Control in Complex Structures
(The American Society of Mechanical Engineers (ASME), 1996)This paper describes a numerical study of mechanisms for controlling all six degrees of freedom in localized areas of a complex structure. In localized vibration control, the controller attempts ... -

(The American Society of Mechanical Engineers (ASME), 1996)This study develops a new accurate method for finding the natural vibration frequencies of plates with cutouts. The method is based on replacing the plate with a cutout by a rectangular plate. ... -
Modeling and Analysis of the Intermediate Shaft Between Two Universal Joints
(The American Society of Mechanical Engineers (ASME), 1996)Unlike a single universal joint, in which the output shaft rotates with a fluctuating speed depending on the misalignment angle, a double universal joint is used to connect two offset shafts. ... -
Wave Mixing Effects on a Periodically Ribbed Cylindrical Shell
(The American Society of Mechanical Engineers (ASME), 1996)An examination of the response of a periodically ribbed cylindrical shell shows several effects due to the mixing of fast and slow waves on the shell. In wavenumber-frequency space, this mixing ... -
