RISClosed-Form Transient Response of Distributed Damped Systems, Part I: Modal Analysis and Green’s Function Formula
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An analytical method is developed for closed-form estimation of the transient response of complex distributed parameter systems that are nonproportionally damped, and subject to arbitrary external, ...
Closed-Form Transient Response of Distributed Damped Systems, Part II: Energy Formulation for Constrained and Combined Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The transient response analysis presented in Part I is generalized for distributed damped systems which are viscoelastically constrained or combined with lumped parameter systems. An energy ...
Transient Response of Inductrack Systems for Maglev Transport: Part I—A New Transient Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As a new strategy for magnetic levitation, Inductrack systems with Halbach arrays of permanent magnets have been applied to Maglev trains and intensively researched in various projects. In an Inductrack system, the magnetic ...
Parametric Vibration of a Flexible Structure Excited by Periodic Passage of Moving Oscillators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flexible structures carrying moving subsystems are found in various engineering applications. Periodic passage of subsystems over a supporting structure can induce parametric resonance, causing vibration with ever-increasing ...
Transient Response of Inductrack Systems for Maglev Transport: Part II—Solution and Dynamic Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In Part I of this two-part paper, a new benchmark transient model of Inductrack systems is developed. In this Part II, the proposed model, which is governed by a set of non-linear integro-differential governing equations, ...
A New Approach to Transient Vibration Analysis of Two-Dimensional Beam Structures at Medium and High Frequencies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Transient analysis of medium-frequency (mid-frequency) and high-frequency vibrations plays an important role in the research and development of complex structures in aerospace, automobile, civil, mechanical, and ship ...
On Singularity of Rigid-Body Dynamics Using Quaternion-Based Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is well known that use of quaternions in dynamic modeling of rigid bodies can avoid the singularity due to Euler rotations. This paper shows that the dynamic response of a rigid body ...
Vibrations of Flexible Multistage Rotor Systems Supported by Water-Lubricated Rubber Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flexible multistage rotor systems that are supported by water-lubricated rubber bearings (WLRBs) are seen in various engineering applications. Vibration analysis is important to design and performance of such dynamic ...
Addenda to “On Singularity of Rigid Body Dynamics Using Quaternion Based Modelsâ€
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Although quaternions are singularityfree in modeling and analysis of rigid bodies in threedimensional motion, description of torques may lead to unbounded response of a quaternionbased model. This paper gives theorems on ...
Analysis of Ring-Stiffened Cylindrical Shells
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new analytical and numerical method is presented for modeling and analysis of cylindrical shells stiffened by circumferential rings. This method treats the shell and ring stiffeners as individual ...
