(The American Society of Mechanical Engineers (ASME), 1995)Procedures are described for doing: (a) transient three dimensional structural acoustics computations, using a combination of modal and finite element techniques in space and explicit integration ... -
Geometrically Nonlinear Formulations of Beams in Flexible Multibody Dynamics
(The American Society of Mechanical Engineers (ASME), 1995)In this paper, the equations of motion of flexible multibody systems are derived using a nonlinear formulation which retains the second-order terms in the strain-displacement relationship. The ... -
On Vibrations of a System With an Eigenfrequency Identical to That of One of Its Subsystems
(The American Society of Mechanical Engineers (ASME), 1995)The free vibrations of a complex system with a natural frequency identical to that of one of its subsystems is discussed. Such eigenvibrations need special consideration in many modal synthesis ... -
Modal Controllability and Observability of General Mechanical Systems
(The American Society of Mechanical Engineers (ASME), 1995)Controllability and observability are studied for general mechanical systems with combined effects of damping, gyroscopic and circulatory forces. A new modal analysis is proposed to represent the ... -
Time Domain Modeling of Linear Viscoelasticity Using Anelastic Displacement Fields
(The American Society of Mechanical Engineers (ASME), 1995)A time domain model of linear viscoelasticity is developed based on a decomposition of the total displacement field into two parts: one elastic, the other anelastic. The anelastic displacement ... -
Modeling Fluid Inertia Forces of Short Journal Bearings for Rotordynamic Applications
(The American Society of Mechanical Engineers (ASME), 1995)It has been recently suggested that fluid inertia may play an important role in the dynamic behavior of rotors supported on journal bearings. This paper presents a model for fluid inertia ... -
Natural Vibration of a Cavity Backed Rectangular Plate Using A Receptor-Rejector System Model
(The American Society of Mechanical Engineers (ASME), 1995)Forced vibration of a cavity backed rectangular plate is widely used to study the physics of noise transmission into an enclosure. In this context, the cavity backed plate is a dynamical ... -
On the Geometric Stiffness Matrices in Flexible Multibody Dynamics
(The American Society of Mechanical Engineers (ASME), 1995)A flexible branch body in a multibody chain undergoing large overall motions experiences geometric stiffening effects due to its own motions and interbody forces arising from bodies outboard of ... -
Modal Parameter Estimation for Piezostructures
(The American Society of Mechanical Engineers (ASME), 1995)This paper is motivated by the need for consistency between piezostructure measurements and existing modal analysis approaches. Fundamental relationships are developed which reveal that the existing ... -
Forced Harmonic Response of a Continuous System Displaying Eigenvalue Veering Phenomena
(The American Society of Mechanical Engineers (ASME), 1995)Prior studies of self-adjoint linear vibratory systems have extensively explored the free vibration phenomena associated with veering of eigenvalue loci that depict the dependence of natural ... -
Self-sensing Active Vibration Control using the Moving-Coil-Type Actuator
(The American Society of Mechanical Engineers (ASME), 1995)Active vibration control requires a velocity signal which is fed back to the force actuator to produce the damping force to the structure. Usually a gap sensor is used to detect the displacement ... -
