Three New Methods of Modal Identification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The identification of linear systems based on their dynamic responses has been the object of a great number of studies. In this work, we propose three new identification procedures which can ...
Response of Periodic Systems to a Moving Load
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The motion of a beam or a plate resting on an elastic foundation and subjected to a moving load has been studied by numerous authors. But the extension of these studies to the case of ...
Structural Damping by Slip in Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The analysis of slip in riveted or bolted joints during harmonic excitation has been the subject of much research. However, in the case of plates the slip is induced by in-plane forces which ...
A Method of Damping Synthesis From Substructure Tests
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The assembly of damped linear structures along continual interfaces in order to achieve a damping synthesis may pose problems, because assembly methods are ill-conditioned when there is a high ...
Optimal Preview Semiactive Suspension
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper examines an optimal preview semiactive suspension of a quarter-coach model moving along randomly profiled track. This optimal computer-controlled suspension is designed only to dissipate ...
Dynamic Substructuring Based on a Double Modal Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Modal synthesis methods have long been studied because the use of generalized coordinates makes it possible to reduce calculation costs. Our approach uses modes to describe each part of the ...
Improvement of a Nonparametric Identification Procedure Used in Nonlinear Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The advantage of nonparametric identification methods based on the use of approximations of the restoring forces is that they do not require the a priori knowledge of a model for the nonlinear ...
Component Modal Synthesis Methods Based on Hybrid Models, Part II: Numerical Tests and Experimental Identification of Hybrid Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A double modal synthesis method in which compatibility conditions at substructure interfaces are ensured by the introduction of loaded modes is presented in this study. These loaded modes, which ...
Component Modal Synthesis Methods Based on Hybrid Models, Part I: Theory of Hybrid Models and Modal Truncation Methods
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The assembly of structures along continuous boundaries poses great difficulties for expressing generalized boundary coordinates in modal synthesis, especially in the context of experiments. In order ...
The Role of Damping and Definition of the Robust Damping Factor for a Self-Exciting Mechanism With Constant Friction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a linear two-degree-of-freedom model in order to analyze friction-induced instabilities that are governed by modal interaction. The role of structural damping on flutter ...
