RISVibrations 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 ...
Optimal Vibration Reduction of Flexible Rotor Systems by the Virtual Bearing Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a new approach to optimal bearing placement that minimizes the vibration amplitude of a flexible rotor system with a minimum number of bearings. The thrust of the effort is the introduction of a virtual ...
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)

On Jump Discontinuities in Internal Forces of Flexible Structures Carrying Moving Subsystems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Combined systems, which are flexible structures carrying moving subsystems, are seen in various applications. Due to structure–subsystem interactions, the structure in a combined system encounters jump discontinuities in ...
Nonlinear Feedback Control of the Inductrack System Based on a Transient Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As a new strategy for magnetic levitation envisioned in the 1990s, the Inductrack system with Halbach arrays of permanent magnets has been intensively researched. The previous investigations discovered that an uncontrolled ...
