Design and Modeling of Viscoelastic Layers for Locomotive Wheel Damping [PDF]
Vibration, 2021 Rail–wheel interaction is one of the most significant and studied aspects of rail vehicle dynamics. The vibrations caused by rail–wheel interaction can become critical when the radial, lateral and longitudinal loads of the vehicle, cargo and passengers ...

Viscoelastic damping design – Thermal impact on a constrained layer damping treatment
Materials & Design, 2021 Constrained layer damping treatments have been commonly used for vibration damping. The included viscoelastic material exhibits high damping potential that is retrieved under shear deformation.

Design and Analysis of a 1D Actively Stabilized System with Viscoelastic Damping Support
Actuators, 2019 Passively magnetically stabilized degrees of freedom yield the benefit of reduced complexity and therefore costs. However, the application of passive magnetic bearings (PMBs) also features some drawbacks.

Development and Modeling of a Novel Magnetorheological Elastomer Isolator in Hybrid Mode with a Compression–Shear Hybrid Fractional-Derivative Parametric Model [PDF]
SensorsMagnetorheological elastomers (MREs) are composed of soft silicone rubber, carbonyl iron particles (CIPs), and various additives. This study designs and fabricates a novel hybrid-mode MRE isolator that can operate in both compression and shear modes ...

A Group-Enriched Viscoelastic Model for High-Damping Vitrimers with Many Dangling Chains
MaterialsClassical viscoelastic models usually only consider the motion of chain segments and the motion of the entire molecular chain; therefore, they will cause inevitable errors when modeling self-healing vitrimer materials with many group movements. In this paper, a group-enriched viscoelastic model is proposed for self-healing vitrimers where the group ...

A Mixed Finite Volume Element Method for Time-Fractional Damping Beam Vibration Problem
Fractal and Fractional, 2022 In this paper, the transverse vibration of a fractional viscoelastic beam is studied based on the fractional calculus, and the corresponding scheme of a viscoelastic beam is established by using the mixed finite volume element method.

Semilinear wave models with friction and viscoelastic damping [PDF]
Mathematical Methods in the Applied Sciences, 2020 In this paper, we study the global (in time) existence of small data solutions to the Cauchy problem for the semilinear wave equation with friction, viscoelastic damping, and a power nonlinearity. We are interested in the connection between regularity assumptions for the data and the admissible range of exponents p in the power nonlinearity.

Modeling of unsteady friction and viscoelastic damping in piping systems [PDF]
IOP Conference Series: Earth and Environmental Science, 2012 In real systems, the phenomena, such as pipe-wall viscoelasticity, unsteady friction or fluid structure interaction induce additional damping and dispersion of transient pressure waves than that defined by classical waterhammer. In this paper, unsteady friction models and viscoelastic damping models will be presented and a theoretical formulation of ...

REDUCTION METHOD APPLIED TO VISCOELASTICALLY DAMPED FINITE ELEMENT MODELS [PDF]
Proceedings of the 4th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2013), 2013 This paper is devoted to procedures for finite element modelling of structures incorporating viscoelastic materials, with emphasis placed on reduction methods intended for the reduction of the order of the finite elements matrices of the damped systems. This work focuses the use of Guyan reduction method. To account the frequency-dependant behaviour of
