Abstract In this paper, the transverse dynamic hysteretic damping characteristics (HDC) of a serpentine belt are investigated. The variable stiffness and variable damping model (VSDM) constituted of a variable-stiffness spring and a variable-damping damper is developed to estimate the HDC of the belt.

Suggestion of MSTV (Modified-Stick-Transition-Velocity) model for hysteretic damping mechanism
Journal of Mechanical Science and Technology, 2008To decrease vibration and noise in washing machines, lubricated friction dampers were installed. Although the structure of the friction damper is simple, it was not easy to develop a mathematical model for the dynamic behavior of the lubrication damper.

Abstract In engineering practice, both viscous and hysteretic damping models are usually employed to characterize damped dynamic properties of linear mechanical systems, the identification of which has long been an active area of research in experimental modal analysis.

APPROXIMATING THE HYSTERETIC DAMPING MATRIX BY A VISCOUS MATRIX FOR MODELLING IN THE TIME DOMAIN
Journal of Sound and Vibration, 2002The paper is concerned with modelling the dynamic behaviour of a structure with damping. Hysteretic damping is commonly accepted to be reasonably accurate in some circumstances, but can only be applied directly in the frequency domain. Dynamic (time) behaviour, however, is most conveniently predicted by a viscous model.

A model for hysteretic behavior of rhombic low yield strength steel added damping and stiffness
Computers & Structures, 2005The Low Yield Strength Steel (LYS) has the superiority over long period of low cycle fatigue, high strain hardening rate and impressive ductility to overcome the local fracture problem existing in regular A36 steel plate. With elastoplastic characteristics and experimental verification, it becomes a good material considered for added damping and ...

This paper presents a hydro-mechanical model for hysteretic damping force prediction of an electrorheological (ER) damper which can be applicable to a small-sized passenger vehicle. A mathematical model which well describes physical flow motion of the hydraulic system is formulated.

AN ENERGY BASED APPROACH TO MODELLING HYSTERETIC DAMPING
The use of viscous damping has been long proven ineffective for the prediction of the seismic response in systems where high nonlinearities are expected. This paper presents a novel modelling approach for damping in structures. This model builds on the reduced hysteretic model proposed by Akiyama and uses a hysteretic plastic hinge as an energy ...openaire +1 more source
IABSE Reports
<p>In time-history response analysis of elastic-plastic systems, common viscous damping models yield unintended spurious damping forces. A previous study exhibited thirteen different damping models resulted in different elastic-plastic response of a 5-degree-of-freedom system assigning a bi-linear hysteresis model. This paper expands on that work
