An Optimized Efficient Galerkin Averaging-Incremental Harmonic Balance Method for High-Dimensional Spatially Discretized Models of Continuous Systems Based on Parallel Computing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Modern computers are generally equipped with multicore central processing units (CPUs). There has been a great interest to introduce a parallelized harmonic balance method to make full use of computing resources and improve ...
Detection of Damage in Space Frame Structures With L Shaped Beams and Bolted Joints Using Changes in Natural Frequencies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is difficult to use conventional nondestructive testing methods to detect damage, such as loosening of bolted connections, in a space frame structure due to the complexity of the structure and the nature of the possible ...
Detecting Loosening of Bolted Connections in a Pipeline Using Changes in Natural Frequencies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Loosening of bolted connections in a structure can significantly reduce its loadbearing capacity. Detecting loosening of bolted connections at an early stage can prevent failure of the structure. Due to the complex geometry ...
An Accurate Singularity Free Formulation of a Three Dimensional Curved Euler–Bernoulli Beam for Flexible Multibody Dynamic Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An accurate singularityfree formulation of a threedimensional curved Euler–Bernoulli beam with large deformations and large rotations is developed for flexible multibody dynamic analysis. Euler parameters are used to ...
A New Locking-Free Formulation of a Three-Dimensional Shear-Deformable Beam
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new locking-free formulation of a three-dimensional shear-deformable beam with large deformations and large rotations is developed. The position of the centroid line of the beam is integrated from its slope that is related ...
Parametric Instability in a Taut String With a Periodically Moving Boundary
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Parametric instability in a taut string with a periodically moving boundary, which is governed by a onedimensional wave equation with a periodically varying domain, is investigated. Parametric instability usually occurs ...
Dynamic Stability of a Class of Second Order Distributed Structural Systems With Sinusoidally Varying Velocities
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Parametric instability in a system is caused by periodically varying coefficients in its governing differential equations. While parametric excitation of lumpedparameter systems has been extensively studied, that of ...
An Accurate Spatial Discretization and Substructure Method With Application to Moving Elevator Cable Car Systems—Part I: Methodology
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A spatial discretization and substructure method is developed to accurately calculate dynamic responses of onedimensional structural systems, which consist of lengthvariant distributedparameter components, such as strings, ...
An Accurate Spatial Discretization and Substructure Method With Application to Moving Elevator Cable Car Systems—Part II: Application
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper uses the methodology developed in Part I of this work to study the longitudinal, transverse, and their coupled vibrations of moving elevator cablecar systems. A suspension cable is a onedimensional lengthvariant ...
Dynamic Analysis of an Elevator Traveling Cable Using a Singularity-Free Beam Formulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A round elevator traveling cable is modeled using a singularity-free beam formulation. Equilibria of the traveling cable with different elevator car positions are studied. Natural frequencies and the corresponding mode ...
